They don't identify with Mexicans and vice versa but they foolishly considered people that look like them to be the same as them. That turned out not to be true. So they've come to the conclusion that it's not in their interest to be pro immigration because they are competing with another group that takes advantage of their struggle and position but does not intend to contribute to their community. It's not in the black community to support immigration and they should make that clear before voting Democrat.
