If no one can tell the man in the ladies toilet is a woman he's not going to trigger any of the "he's a man" alarm bells that clang in my head when I see a bloke.
HOWEVER very very very very few actually pass as women.
The transwoman might think he does because all his friends have been being all nice and kind and assuring him he totally passes as a woman "You go girl!
The transwoman might think the heavy filters he uses in his selfies means everyone sees him like the filtered image of himself.
The transwoman may even be convinced he passes as a woman enough that when he stands in front of the mirror he doesn't see 6 foot 4 Dave with the bulge in his crotch, chest hair, male pattern baldness, a beard and a beer gut but a 5ft 4 svelte woman called Sandra instead.
The transwoman might think taking cross sex hormones, having bags of silicone inserted under the skin on his chest, having his dick inverted and wearing what he thinks are 'women's' clothes and make up with a nice shade of lippy means he truly is now a woman.
But I'll bet the majority of them are clocked as transwomen the second they walk in to most rooms.
But it's all irrelevant. A transwoman is a man and quite frankly I don't give a shiny shit if I upset his fragile sense of self or where he actually does end up going to the toilet. Not my problem to solve as long as he stays the fuck out of the women's toilets.
I shouldn't have to keep him out of the women's toilet, he should bloody well keep himself out because he absolutely, even if he is one of the miniscule number of those men who passes as a woman, knows he isn't and that he is a man.
