I think it's a little ridiculous to shy away from calling yourself a feminist because people would be upset to hear it, knowing that any ideas you spout that aren't as monogamous and heterosexual as possible will get pushback either way.
Like, shit, I'm a feminist and I own that shit. If someone thinks all feminists = radfems, then they're either stupid, or not worth debating the idea with because they get all their info from psychotic youtubers. The number of radfems is astronomically low in comparison to actual feminists that I think even acknowledging them beyond "they exist by law of numbers" is overstating them.
