You can always tell eh? 😉
YABVU. Ridiculous. This is exactly what happens though. All this vitriol and bigotry means that trans people are hated on just for existing. Transmen often need period products, transwomen often need bras. Not new, not an opinion, shouldn't be controversial. And frankly if more transmen are seen proudly advertising period products, maybe the dysphoria and discomfort that many of them feel about periods would be less.
Editted to remove pronouns - shan't assume. Good point made above that AFAB people may still grow facial hair naturally.
