I mostly meant it as a joke. I don't date or have sex, so its not something I'd seriously consider.
But I also suspect I'd have a hard time jiving with someone who strongly identifies with their AGAB. Personally, I sorta feel like gender is BS and cis people caring about it is weird. If they only tepidly identify with it, that's fine. In a non-transphobic world, I'd hold trans people to the same standard, but since transphobia is prevalent, trans pride ought to exist as a counter force and trans people at least inherently challenge some of the worst aspects of gender as conceptualized by transphobes.
