Basing it on race is too simple, IMO. If someone has a high IQ, I want them in my country, and to settle down here, and then mix in as much as they can tolerate. Race only becomes an issue if they're dumb. Not trying to throw insults at anyone - I just prefer to cut it that way instead.
Discussion
I'm not talking about immigration in an abstract way.
I'm talking about the daily experience of people living life.
in which case
if you're stupid you probably want to hang out with other stupid people
who look like you and have similar cultural assumptions.
And I'm not saying it's 100%
people come together all the time crossing cultural and racial boundaries.
But by and large
it's just *easier for everybody to live amongst people who are similar
True. I combine all my social assertions with localism - only a community has any right to make decisions about that particular community. How much immigration they allow, or with what criteria, is up to them. No one in Israel should be telling my town in Texas to accept refugees, or insert whatever locations. That's not because I don't want to help refugees - I actually do - but a foreigner telling my community anything is an act of war in my view, and I would absolutely respond to any such imposition with war, if I had such authority (which I don't want).
