Like, if I want to dismantle hierarchical structures that oppress me and all that jazz, but I know jackshit about class because I don't read or participate because I just gotta work my day job day in and day out, am I not a leftist?

Well, if you're openly what's called "a baby leftist", then yeah, I get it, nothing wrong with that, we all start somewhere, but at least there should be a drive to get informed. My comment was specifically towards people who use specific labels such as anarchist or communist without really knowing what they're talking about.
