Taste-based discrimination, which is how we usually think of hatred and bigotry, is not individually irrational.
To continue the discussion from your previous post, I tend to think about it in evolutionary terms. The rise of cooperative prospering culture is rooted in group/multilevel selection. Migration is bad for group selection. In terms of Intrademic group selection thought of as cultural evolution, the process should be that people change their type to mimic the type prevalent in the successful culture. That's assimilation. The economic thinking you refer to – people want to improve their condition, which improves society through the invisible hand – does not work for collective action.
I mean, sure… Almost nothing in human behaviour cannot be written down as a utility function, in the sense that it violates completeness and consistency. But it is not really how economists think of people, especially in the context of migration decisions.
