I know that the brain scans don’t match this theory but I assume trans people would come up with something “b-but brain scans don’t show all that there is to brain!” or “science is made by white cis men” all over (I mean in a case for those who would accept brain theory as argument, even though it’s faulty). Even though they play with science, using whatever is a suspicion or not, to back their own opinions, a lot of what they promote isnKt actually about science but about feelings. Even though process of feelings is reflected in some way in our neurological system (but of course I won’t elaborate how, I’m not a scientist), feelings are expressed in some varied ways sometimes, due to culture, and it looks like they’re hard to grasp after all. I don’t mean not being able to perceive how someone feels like according to us, I mean it’s hard to fully know why someone feels that way. Because for example, some people might say “this person is angry because they feel being trans is a special identity and those not accepting it are evil far-right bigots, they want to be special or have victim mentality” and the trans person would mention different reasons for being angry.

You got it at the end I think, what I wrote above. It’s not about rationality, it’s about feelings. Even it’s hard to stick to definitions because there will be always someone who understands definition in a different way. I don’t remember where but perhaps on SaidIt I came across a person saying that nowadays the trans label is being applied to everyone who doesn’t fit gender stereotypes in the slightest way. Some portion of woke people will regard that as aspect of trans or any other “opposing” of gender binary. That’s why it’s actually hard to argue with them, they’re more preoccupied with their feelings than facts and use labels and terms that can have infinite possible definitions.

I agree that there is no way to say how “having a gender” feels like. Any woman or man doesn’t go and think “wow, I feel so masculine/feminine today/always”. That’s just nonsense. Trans people, aside from their psychological problems, perceive gender/sex as aesthetic or way of behavior or personality.
