Ah, good point. I tend to clarify, depending on what conversation I'm in...sometimes it's obvious where the lines are and sometimes not. In RL conversation I usually just say "I'm a feminist" without qualifications since I spend (too much) time surrounded by non-feminists. Online I tend to throw in various modifiers like "anti-racist" and "pro-disability-rights" and so forth, except in cases like this where I'm mainly tempted to say "I'm a feminist...but not an asshole like those assholes commenting in that thread!"

What I don't do is say "I'm not a feminist because feminists are (X)," because I don't want to let racist, ableist, heterosexist & cissexist jerks steal feminism.

Maybe "Progressive Feminist" would be more descriptive...?
