I really do miss back when it was considered fucking weird to ask trans people(or anyone who is even a little gnc/has a label you don't understand/is giving you queer vibes)* what their assigned sex at birth is. Like we literally used to roast cis people for this shit, that's legit why the "what's in your pants" meme exists, but somehow we've reached a point where a very vocal portion of the online trans community genuinely thinks you owe people this information so they can make insane generalizations about you and your life and if you refuse that's cause for suspicion and I really shouldn't have to explain how fucked that is.
Interrogating people about what's in their pants is transphobe/terf/transmed shit. "If you have nothing to fear you have nothing to hide" is fed shit. Tbh "you owe me personal information about your body and medical history" is ableist and intersexist shit. Sex and/or gender tells you literally nothing concrete about a person and there is no world where you are owed this information. Can we cut this shit out and go back to judging people by their words and actions instead of what some random doctor decided their body looks like when they were a squishy baby, you know, like normal people? Please??
*It's also wildly intersexist but unfortunately I don't think we've ever reached a point of collectively accepting that it's horrid to ask intersex people unprompted questions about their bodies and medical histories. You are absolutely not owed any of that information for any reason, especially given that medical history typically goes hand in hand with profound trauma due to how normalized medical abuse against intersex people is, and everyone needs to get that through their heads yesterday. If they want to share they can and will, aside from that it's none-ya.
