First, some of history's worst violence, civil wars, and worst atrocities occurred in relatively homogenous nations - the civil wars, internal conflicts, and revolutions in China, European Russia...even Japan has had way more than its fair share of internal violence and atrocities. The French Revolution was notorious for violence and inhumanity.
Well yeah, because for most of history, people only had contact with people of the same race. And of course there are other things that cause tension. Politics, religion, ethnicity, culture, and so on.
None of this changes the fact that homogeneous societies generally function better than diverse ones. And if people fight over religion and ethnicity, why add race to the equation? That only makes things worse.
Antiquities most catastrophic war were the peloponnesian wars- waged entirely among Greeks.
And look what happened when the Greeks were threatened by the Persians. They came together as Greeks to defend their land from a culture that was even more distant than their own. The same thing would later happen with all the German tribes uniting against the Romans.
I would say that a careful study of the historical record would actually show that the most death and most apocalyptic civil wars and revolutions occurred in relatively homogenous China and European Russia.
Yes, and in America, most murders are between people of the same race because those are the people they are more likely to be around. Again, for most of history, people only had contact with people of the same race.
Second, assimilation does happen by the second generation and most defintely by the third. I have seen it up close and first hand.
Blacks, American Indians, Jews, and Mestizos have all been in America longer than most white ethnicities. And yet those four non-white groups are still far less assimilated than literally every white ethnicity.
Why are Blacks constantly fighting for representation in government and media? Aren't they just American? Why should they care how many Blacks are at the Oscars if we're all just Americans? The truth is, Blacks don't consider themselves American and probably never will.
But the bottom line is, if you do not want to live around Jews, hispanics, Muslims, or blacks, you can always live in northern Idaho, or any of the places this great nation has which are overwhelmingly white. A lot of other people are perfectly fine living in San Francisco, New York, Atlanta, and other enthnically diverse areas.
And what happens when non-white people start filling up the North-West? Will we be able to still have our white neighborhoods? Or will the government force us to sell houses and rent apartments to non-white people? White people do not have freedom of association anymore because we made the mistake of allowing the non-white minority to get too big.
I believe in freedom of association. You want to live in a multiracial neighborhood, you want to hire people of every race in your business, then you should have that right. But white people should also have the right to refuse to do these things.
