Leftists who view everything as a class issue get their asses handed to them at the polls every time. Yes, you can come up with some complicated strained logic for why things like homophobia or racism are a class issue, but that just doesn’t jive with what people experience in their actual lives. And you can stamp your feet and say that class issues are the most important issue, and everything else is secondary. Meanwhile, targeted minority groups will ignore you and focus on their actual real most important issues.
