Yeah, they usually don't identify as "lesbian" per se, but some vague Tumblr thing like "demiflexible pansexual" or whatever so they get cool queer points and can cry about oppression when you call them out on their shit. I've run into plenty of them on dating sites and in real life. They aggressively hit on fit women, under the delusion that we have lower standards than men and will coddle them. Then they realize--nope--we hate them, too. So then they date other fat blobs.
