Reading this thread, it just struck me very clearly how odd it is that TRAs and those who sympathise with them believe that a trans person's idea of what makes a man or a woman is automatically the authorative one. The person who has not in fact lived the life is given more credence than the ones who have.
Trans people say "my experience is this, and that's how I know I'm a man/woman". Thousands, millions, maybe billions of other people say "ok, but surely I am also a man/woman and my experience isn't that at all, it's this."
But for TRAs the second set of people have no value at all. The first statement carries all the truth and everyone else is supposed to say "oh ok, I didn't understand myself and my own life and my own experiences, it must indeed be as the transperson said".
The suggestion that perhaps it's the trans person who didn't understand themself and their own life and their own experiences is treated as utter shocking blasphemy, triggering the raining down of every horror that can be invoked. And yet it's exactly how TRAs and their sympathisers treat anyone who disagrees with them.
The double standards are fascinating.
