Hate of a whole race of people, hate of a whole set of people of certain sexual orientations or gender identitie, that kind of hate is projection. Im insecure in myself, in my identification with my culture, in my sexual orientation, in my gender so I project hatred onto you because Im not real sure that if I dont, I wont hate myself.
So, heres the thing about hate of difference: It says everything about the hater, and nothing about the hated.
