If she's not from Lesbos then it's just sparkling dyke

I know it's a joke but it really should be the other way around

Yes, non-lesbian Lesbians (proper noun) sometimes begrudge tourists taking their demonym. The lesbian community online tries to be generally inclusive, (with smaller gatekeepy sects) so there is a conflict.

Still, Lesbians do like lesbian tourism money, if not always the tourists, themselves.
