I think it's a lot more black and white being trans than people realize and I have my own pet theories about what gender euphoria /dysphoria is that I observe as being two independent factors.

Half of the problem I think in reaching people is that the vast majority of cis people don't have an observed internal gender preference. We are trying to build empathy with something we as trans people assume they have too - but maybe only a small minority of cis people experience it. I don't think we actually understand cis people, we just assume a bunch of things about them using trans people as a false opposite.

Thing is... If I am correct, the assumed massive earth shaking regret of what would happen if a cis person went through gender reassignment... Is they might just adapt and be fine.
