Actually the root of human bigotry is xenophobia: that is, the fear of anything that is alien, or different to them. This is what causes bigotry and
racism. Anything that is different is not known, and a possible threat. This is what causes tribalism.
In the modern age you'd think humans have progressed enough to learn to live with each other and overcome these petty differences.
But somehow, I don't think that they can.
