One thing that is true about Americans on the whole is that they don't even know what they want. Take the First Amendment. You can't fling a cat without hitting someone in favor of free speech. For all our talk about protecting our freedoms, we're more interested in keeping ourselves from being inconvenienced.
Truth be told, most people are idiots.
For example, at most any outdoor concert, you will see flash bulbs going off everywhere. But back to my point, regardless of how intelligent someone else's form of expression is, we generally don't want to hear it. In fact, some are so pervasively unpopular, that there is actually legislation against them. Those poor guys ignited a whole debate about the need to censor obscene material in music. This saves parents the chore of actually listening to the music to see if they find it objectionable.
