Trans men aren't more accepted or tolerated, a huge portion of the fear mongering about trans youth is about "cutting off healthy breasts" and "ruining their fertility." Literally just look at the cover of Irreparable Damage.

I'm trying to not be a dick here but this is a fairly large point of trauma for me: what do you imagine happens when a trans man shows up in a doctor's office, possibly without a legal name change, almost certainly marked as female in their system? Because I can assure you it's not that you get totally respected and treated as a normal dude.

Trans men are threatening to patriarchy by virtue of being "women" who do not stay in their place.
