Let people express however they want! Social gender norms are just arbitrary, sexist, oppressive bullsh*t! Having a certain kind of body..? Only means you've got that kind of body. That's IT! And it should put zero restrictions on your style, or interests, or personality, or behavior, or attractions, or WHATEVER!! Being a super masculine, lesbian female is not wrong in any way! Just like being an extremely feminine man is not wrong in any way either! But: that still does not mean you're "really" the other sex! And I'm hella tired of transgender activists trying to deny and erase basic biology! Especially because that's been the whole reason for female oppression to begin with, y'know..?
If some people still NEED to transition, for mental health reasons, I accept that. But it should be a last resort, more than anything else. And pretending as if people are "really" the other sex, just because they don't fit social gender norms..? Is pure bullsh*t, if you ask me.
Someone who comes at this neither from the perspective of conservative fundie religion, NOR from the perspective of trans ideology gone mad, on steroids! But instead, from the perspective of 2nd wave feminism. (I used to be a *very* good and unquestioning little trans ally, before I started reconsidering things.)
