Could you answer the question:
What are your criteria for someone to be a transwoman and therefore 'accepted as a woman' then?
I'll expand on it a little if you like.
If you don't believe in self-id, as you have stated, then at what point does a male become a transwoman and therefore, in your opinion, have the right to be accepted as a woman. Does that male had to have had surgery? Top and bottom, just top? Do they have to have been taking hormones? For a certain period of time? Or do they just need to wear what we would stereotypically class as 'woman's clothing', wigs, make up etc?
What, in your opinion, makes a transwoman a woman?
