The thing is when you’re bisexual, you’re not really surprised when a straight person is biphobic. Sure it sucks and you’re like “well fuck you too dude” to whoever the prick is; but it’s not so astonishing.
Biphobic gay people on the other hand, actually hurt like a motherfucker. Like bro you’re supposed to be on my side??? Like even “my people” can’t accept me?? That hurts so much more than some random dude who expects a threesome.
