Let's take a look at a dictionary definition of culture: "the way of life, especially the general customs and beliefs, of a particular group of people at a particular time" (http://dictionary.cambridge.org/dictionary/british/culture)

Now, note the "particular group of people" part. A person can be a member of more than one group. Some groups are sub-groups of others; some overlap with others.

For example, I am an American, and as such I have been brought up in American culture, with many of the traditions and ideals that that entails; Thanksgiving, the 4th of July, a strong belief in civil liberties, and a love of strawberry rhubarb pie.

American culture is also a subset of Western European culture, with influences from Catholic and Protestant branches of Christianity, so while I am not myself Christian, I celebrate Christmas and Easter and have many Christian influences on my values and life.

However, I am also a member of other cultures. My most recent ancestors to travel to the US were Scottish; and so Scottish culture is also part of my culture, but not most other people in the US. I wear kilts to weddings, and have an uncle and cousin who play bagpipes at weddings and funerals. That's a part of my culture, but that is not a part of overall American culture.

I'm also a software engineer and computer geek, and involved in free software, advocacy for civil liberties online, advocate for strong encryption and privacy, and the like. This is a particular subculture that tends to promote strong protections for individual privacy and liberty, while openness and transparency on behalf of institutions such as corporations and governments. This is not part of mainstream American culture, but it is part of my culture; and this particular subculture spans multiple countries as well, so in many of these ways, I have more cultural values in common with a Brazilian or German who is also involved in these communities than I do with the average American.

There are many other subcultures I could describe myself as a member of. And the same goes for anyone you ask. "Culture" is not one big, monolithic thing with clear boundaries. Because it is a set of customs and beliefs shared with a group, that set can be larger or smaller, and stronger or weaker, depending on how big of a group you choose.

> And if "multiculturalism" whatever that is, is so great, you'd think someone would have come up with support for that notion by now beyond "Ethnic food!"

Food is a pretty fundamental part of any culture. As something that is necessary for sustaining life, it's something that everyone does. In almost every culture I've seen, meals are a large part of fostering community, of strengthening social bonds. You have meals with family, with friends, with coworkers. "Breaking bread" is a term rich with culture connotations of mutual trust, peace, welcoming, because sharing food with someone is so important; and the same holds in many other cultures, one of the most generous and welcoming things you can do is invite someone to your table and share your food with them.

So don't be so quick to dismiss "ethnic food" as an important part of multiculturalism. Food is in many ways the heart of of a culture, and exploring the food culture of another people can be a strong way to share something with them.

However, multiculturalism can extend far beyond that as well.

The musical heritage of America is quite strongly multicultural. Ragtime, blues, jazz, R&B, and hip-hop all have their roots in black culture in the US, but have had enormous influences in white culture as well. Of course a large amount of American musical traditions comes from Western European classical and pop traditions as well, and then there are a variety of folk traditions, such as Celtic, that have been integrated into the mainstream through bluegrass and country music.

But there's a lot more than just that. A large number of cultures have made substantial impact on film in America. Many of our "Western" genre is actually a product of Italy; but that in turn influence Akira Kurosawa in Japan, with Samurai westerns such as Yojimbo. His work has also influenced Western work, where The Magnificent Seven is a western remake of Kurosawa's Seven Samurai, and his The Hidden Fortress is one of the major influences on Star Wars.

Let's see, getting back to day to day life, Jewish culture has also had a fairly large impact; from Yiddish, we get words like "schmuck", "chutzpa" and "klutz". We also get bagels (oops, back to food again),

On the musical front again, some of the best American music like Gershwin's Rhapsody in Blue had roots in Western classical tradition, jazz, and klezmer, traditional Ashkenazi folk music.

I could go on, but man, detailing all of the positive effects of multiculturalism on American society could fill up hundreds of volumes of books, not just a single comment on HN.

> A murder seems to be ipso facto a hate crime.

That is not what is meant by the term "hate crime." Simply redefining a term that has a particular meaning to mean something else does not really add to the discussion.

I'll quote from Wikipedia:

> In both crime and law, hate crime (also known as bias-motivated crime) is a usually violent, prejudice motivated crime that occurs when a perpetrator targets a victim because of his or her perceived membership in a certain social group. Examples of such groups include but are not limited to: ethnicity, gender identity, disability, language, nationality, physical appearance, religion, or sexual orientation.

A "hate crime" is not simply any violent crime. It is a crime in which the attacker was motivated by their perception of the victim's membership of some other group.

There are several things that can motivate a criminal to commit a crime. Poverty, greed, hatred of a particular group, hatred of a particular person, sheer anti-social tendencies, and I'm sure many other motivating factors. Only one of these falls under the term "hate crime" as it is commonly defined; those crimes in which hatred of a particular group of people is a primary motivator.

If you look at the statistics I cited in a previous comment, while it is true that black on white murder happens more often than white on black, white on white murder far surpasses either (and likewise, black on black). No amount of arguing about the black on white vs. white on black levels of crime will make these intraracial crimes go away, and the levels of intraracial crime is a very strong signal that racial animus is not actually the motivation for the majority of crime that occurs.

The reason it is important to look at the motivation behind a crime, and not just the statistics about whether a crime happened, is that the motivations can help tell you the best way to reduce that type of crime in the future.

Hate crimes, in the sense of any crime committed on behalf of membership in some group, can be particularly dangerous because they can lead to either prolonged violence between those two groups, or ethnic cleansing or genocide. These types of crimes, when allowed to escalate, have escalated into some of the greatest atrocities of a last couple of centuries. Breaking the chain of hate-motivated violence by discouraging the use of rhetoric of hate, by changing laws that institutionalize disparities between these groups, and by applying harsher penalties to those crimes committed for these reasons, are some ways to deal with these types of crimes.

Crimes committed due to a hatred of a particular person, however, are fairly different. They are usually based on some aspect of those people's relationship; perhaps an abusive domestic relationship, a cheating spouse, or the like. Here, there isn't some group-based animus, but a dysfunctional personal relationship. Here, the better way to deal with the problems are to provide better outlets for change than violence; provide shelters for people to escape from abusive relationships, allow divorce, as it it preferable to violence or murder.

Crimes that are committed due to poverty, to people having as sense of hopelessness and no further opportunity but to turn to crime, are another kind of problem. Here providing better social services, better education, better access to affordable housing, and the like can all help take that pressure off that can push people over the edge.

In all of these cases, the actual perpetrators of actual crimes do need to be punished; there needs to be deterrence as well. However, on a societal level, there can be many things done to reduce the temptation and pressure to engage in criminal behavior. And even on the individual level, knowing someone's motivation for a crime can be important in rehabilitating them and reintroducing them back to society.
