Is it normal to hate multiculturalism?

Blonde hair vs brown hair vs red hair are also physical characteristics, but you deem those to be of no significance, so don't act as if this is an argument based on physicality.

No, that is most certainly not the human instinct. If it were, we would assign social traits to people with different hair and eye colors. Those traits actually do hold more biological significance than skin color. We merely assign skin color significance because skin color was a biological adaptation to living in different parts of the world, and humans are biologically programmed to reject that which is unfamiliar- for good reason.

There is no scientific evidence supporting theories that intelligence levels or hormones are different between races. If you can find such evidence I'd like to see it, but as far as I've read those theories are pseudo-science that was created 100's of years ago in order to justify slavery and wars. Feel free to prove me wrong, with facts and not your opinions. I'm open to read any legitimate articles that you provide, and open to changing my mind should you prove me wrong.
