Agreed. I don't object to the right of association. You can't force people to live together. They have to be allowed to live together and figure out how to live around each other. This can only be done one person at a time through patient and voluntary interaction.

Forcing people to live together will always cause problems without some sort of over-arching, mandatory, cultural demands. Everyone can get along in a barraks because everyone is coerced into suppressing individual rights, required to accept a homogenous code of conduct, and accepts that their position is purely temporary. What actually belongs to them is a forcibly isolated out. In a normal human society, this can't be done. People have to feel each other out.

What the alt-right don't understand is that integration is completely natural for most populations, and is even an aspect of evolutionary biology. There is a point to the argument that diversity is a strength... primarily in genetic diversity as a resistance to disease. Total dissimilarity is what is not a strength. Integration just isn't initially the norm, but over time it happens if no one is trying to draw up boundaries and coerce others. Populations will slowly integrate, and individual people will self-segregate and self-integrate as personally needed. That's a good thing, leave the humans alone, they'll figure it out.
