"Proletariat" and "bourgeoisie", respectively. Identity politics becomes real easy to understand when you recognize that the supposed 'good guys' are bourgeoisie (and their apologists) trying to take self-sufficient peoples and reduce them to proles, and blaming those peoples for all the things the bourgeoisie(-apologists) do themselves. In other worlds, all identity politics is projection on the part of the perpetrators against one group of victims for the purposes of dividing and conquering their victims, lest they rise up against them and string them up.
I dont think the Palestinians are mad at Jews for being bourgeoisie. The identity issue is at the heart of that conflict, its not a proxy for class. If the Palestinians had more money they wouldn't get Israeli citizenship. I guess some identity politics could be proxies for class struggle though.
Edit: That makes literally no sense earlking. If Israel Palestine is a struggle between two bourgeoise then it isn't a class struggle. Its an ethnic struggle like I said above.
The issue at hand in Syria-Palestina is who owns the land and who can be there. It's one group of bourgeoisie slugging it out with the other. That's why it doesn't look like a class issue to you.
