They do accurately represent that definition. The 2% that you see on tumblr doesn't though. Maybe you're getting the minority confused with the majority again
First I don't see any feminists on tumblr, hell with the amount of research of Tumblr I'm still surprised that there are any on there at all.
Second, Strawman fallacy inbound.
I see these 'feminists' all over my forgetin' school, shoving their "IM GAY/TRANS/[InsertRaceHere] RESPECT ME OR ELSE" in literally everyone's faces. Funny enough they've been becoming more and more common since the election. This is why you usually see videos like the "Cultural Appropriated hair' Video in school and on colleges, its because that's where its common, you're not going to see it in the states where no one goes to school.
