What do you mean?
“ Trans men don't just decide they feel male on a whim or because they grew up with brothers or because school discussed gender identity and it's the same for trans women. It's biological part of who they are.”
This makes no sense - what biological part of them is trans? There is, as far as I’m aware, no biological way in which trans people are different. It’s a ‘feeling’, apparently.[/quote]
I suggest you do some research into that. 
As a society we are constantly changing and evolving and that's a good thing. Some of the ways our society behaved in the past and even behaves now are awful and the hope is that people learn and do better. Any group that claims to be something supportive and then rejects and attacks people who don't meet its ideology or don't look the right way or think the right way is never a good thing .
