i disagree that it's biological, to me it's actually much more simple, we just go with whatever pleases us, in my case i love having a feminine appearance and being referred to as the female gender, amongst other things, but i think gender is a social construct
the thing is that society created gender roles, with actions, appearance, mannerisms, etc, that are suitable for those labeled as male and female, and after someone is born they get assigned the male or female label based on whether they were born with a penis or a vagina, and that's it, the person is not allowed to choose which one they prefer (or if they prefer neither or both), and they are expected to accept it, if they don't, they get labeled as having a disorder or a mental problem for not conforming to the majority, everyone is born genderless, gender is learned
gender roles are also destructive to cis people, if they like something that belongs to the other gender, they are made fun of and prejudiced against
i don't think there would be any biological element is there? is there anything biological that defines our tastes? for me it is a matter of what we identify as, of what we want
changing it to gender dysphoria hasn't done much good, being different is still considered bad, a disease, a disorder, apparently we can't just prefer belonging to the other gender (since apparently that's crazy, no one would ever want that right?), also, the treatments didn't change (at least not here), and then there is a lot of red tape to change OUR bodies, to me it just seems like bigotry and prejudice against gender diversity, much like being homosexual was before, now they just need to get over that transgender people are normal too
