I think it's easy for people to say that they don't identify as having a particular gender when they have never experienced gender dysphoria themselves. Easy to believe you're rejecting gender when your body and mind have always fit, albeit subconsciously.
To me 'subconsciously' sounds an awful lot as if you know for many of us our bodies and minds don't 'fit', and you want to claim that they do fit ... we just don't consciously know it. I may be being cynical to say that. But I find it really offensive that someone claims to have a sense of how my body and my brain should fit together.
It is a real thing, that happens in the womb, a hormonal imbalance.
Evidence? I do not think we know enough about the mind. We know a certain about about the brain, but even observing physical differences between brains tells us little about differences between minds.
If the sexes have different bodies, why is it so hard to accept that we might have different brains too?
What do you think the differences are between male brains and female brains? And how does this relate to male minds and female minds?
The suicide rates amongst trans people are horrendous - around a third kill themselves. Are we really to believe that people reach those depths of despair simply because they don't want to conform to stereotypes?
These suicide rates are indeed horrendous. But why on earth do you think people wouldn't be driven to despair by oppressive stereotypes?! I can't imagine much worse than constantly being told you're not normal, that everything that seems natural to you is wrong and misguided.
