"How is believing you were born in the wrong body any more crazy than believing a big guy in the sky created the world and watches everyone?"
At last, something you and I agree on, Earlywalker.
This is precisely how I view this - as a kind of quasi-religious belief. And (it may surprise you to know) if it helps someone conceptualise the world around them and make sense of their lived experience, I'm all for it.
I just don't think I can be compelled to share that belief.
And where quasi-religious beliefs start to have practical consequences for me and other women, I have the right to discuss them and object to the practical consequences being foisted upon me. So for example if a government is majority fundamentalist Christian, and wants to ban abortion, I have a right to protest against this. If a government is majority populated by people who believe TWAW and want to place male-bodied rapists into women's prisons, I have a right to protest against this.
