Could be hormonal disorder for some of those, just sayin'

I have no doubt ....

Is it really, is there evidence apart from this to back it up?

It's in your pants.

Lol!

Look up gender dysphoria

Technically, all genders are mental disorders, it's just that the first two are more accepted.

That makes no sense that would mean genders don't exist

Gender is a human construct. Some beings have p**ises, some have va**nas, that's about it. Inside we're all pretty much the same. If things had played out differently evolutionarily, then we may have all been asexual. What makes people different mentally is how their brains are wired and what chemicals are released into their bodies.

No basically this post was BS and gender doesn't defend people?

No, not at all
