>I'm not the OP but you've lost me as well. What part of what you're saying is supported by data? Any data?

I was pretty clear on what was opinion/experience based and what wasn't. If you can't understand that I can't help you.

>What gave rise to the USA were productive people creating a country for themselves and preventing other people from immigrating there. Immigration was mostly limited to other anglos.

Immigration restrictions are a new thing in the last hundred years or so, people of all kinds immigrated here. Those "productive" people you refer to largely had their success built on abusing and using the minorities that did immigrate here as well.

>One of the most remarkable things happened in Africa, I forget exactly where, where an unbelievably high number of 160IQ+, 170IQ+ school children were found whose parents had immigrated from Britain.

Sources for that.

>What you had in the USA were a high concentration of these outlier geniuses and other very productive people that made a new nation for themselves.

The USA is actually not even in the top 10 based on Mensa, and from what evidence I can find never has had a high concentration of outlier geniuses.

>Is this not a ridiculous statement?

No, its a simple truth.

>The history of the "white man" is filled with producing outlier geniuses that are costly to those around them but benefit the group. These geniuses go their own way, they don't take ideas from others. You don't see these kinds of geniuses elsewhere, for reasons I forget.

You're making hilarious claims, you're gonna have to provide some source for that. History books have nothing backing your world view here, its based on a fairy tale as far as I'm concerned based on what history I do know.

>I'm fairly certain that the consensus among those that have looked into slavery in the USA is that it was nothing but detrimental, slowing down progress. The slaves were well fed and made to work little. Children have been made to replicate the daily work of a slave in the USA and have done it with no issue.

This is completely false and bullshit slavery apologists often repeat.

>It shouldn't come as a surprise to you to learn that the very people that ended slavery are the same people that treated their slaves well.

This is also false

>The slaves that freed themselves before slavery ended integrated surprisingly well, much better than the rest that gained their freedom later. Maybe an IQ difference between those capable of setting themselves free and those not.

Again, mostly BS. There was a significant difference between north and south and much had to do with what scarce education they achieved or were able to get.

>It's a recognized problem in Europe that second and third generation immigrants from the middle eastern countries are integrating worse than their parents.

This is false. its a mass media talking point that's wrong. Look into the studies.

>I don't know man, everything you're saying just seems made up from the spot.

Most of it was opinion, some of it was relating history as we know it. Just about everything you posted is incorrect, outright misleading and much of it sourced or the lies initially came from slavery apologists and those that refuse to actually look at history and accept that with the good a lot of bad also happened.
