"You're so pretty I can't believe your a lesbian" is lesbophobic because it comes from that stereotype that lesbians are only lesbians because they wore too ugly to get a man. Also assumes beauty is something for men which is misogynistic
I used to live at my friends crib who was a cis guy. I asked if it was problem for me (a trans masc w DD's) to walk around the house w no shirt. - He paused for a moment & said ... "If you had perky boobs it would be, but since they're saggy, we're good"😭😭
