sure, that's possible. I'm just going off what I've seen of Trump. It smells a lot like identity/race politics to me. but if your point is that Trump might be deeper than he appears on the surface and I simply haven't done enough research, you very well could be correct; I haven't done a whole lot of research.
One direction I could take my argument is to suggest that race politics goes deeper than economics, and that women can be racist, too.
Another direction, is this idea of "identity politics" - this idea that if I see myself as the sort of person who votes for Trump for social or self-image reasons, that overrides any self-interest I may personally have in the matter, and maybe even what I think is right and just.
but... talking about identity politics is hard, because it quickly becomes circular. If you believe it because your group believes it, why does your group believe it?
I'm particularly poorly placed to understand identity politics in a respectful way, because part of my self-image is that I am the sort of person who doesn't pretend to agree with my friends; the sort of person who has friends who are different, who have different opinions. I mean, I'm sure this self-image is as flawed as anyone else's self-image, and you could poke holes in it all day, but this is my self image, and so the very idea of liking something because the group I identify with likes it seems... negative, perhaps in the same way that immigration seems negative to the trump voter.
