as a gen z, there's a considerable fraction of mostly girls who identify as bi or nb just bc it's "trendy". tbh it's a problem and lowkey trivializes people who actually are those. i think this is what happens when you emphasize a "lgbt community", young people seeking community will join for no other reason.

5% is low, then, for some. But it's far more than OP's 1%, which was my point.
