I know some extremely heavy-chested women will wear some bras to sleep, but yeah, we're not talking sports bras, we're talking bras that offer some sort of support so they can actually breathe. Just like none of us are shoving tampons up our anus to feel more feminine, I guess, no matter our genital configuration.
Speaking of which, yeah. Bold of Alex to come out swinging for Intersex to be a third sex/pure-hermaphrodite when that's literally what intersex activism is opposed to. Intersex conditions are still sex-based. Yes, some intersex individuals possess abnormal cross-sex characteristics, but after a karyotype test their base sex is evident and they are literally exhibiting symptoms of a sex disorder. Co-Opting Intersex Narratives (COINing) is a thing radfems mention often because it's what intersex activists have asked people to respect, which trans rights activists tread right over because fuck 'em!
Trans people who appropriate "AFAB"/"AMAB" labels and act like intersex people exist only to bolster their arguments are some real fuckheads. It's hard to imagine Alex has never before encountered them. What a lazy, nasty shit.
