Yes, obviously ghettoized communities practice mutual aid. So what? If anything, this makes it even harder to do so outside of those communities because makes it sound like mutual aid is only possible within them.

Also, personally, my father came from one of these communities. Despite being the "right" race, he felt ostracized and left. Where does that leave me? Was he "wrong" for not fitting in there? Even if he was wrong, what does that mean I (or literally nearly anyone else not currently in one of these) should do now? Reformism? FOH
