I know a woman when I see one.
And I don't believe in a soul. There is no magical, animating, and gendered spirit. All of your thoughts are generated by the lump of meat inside your skull, because your brain is an organ with the job of generating conscious experience. People who don't think that is true have very limited experience with mental illness, old age, injury, and dementia. I am not going to split hairs with someone on the meat in their head, or the meat in their pants, being more significant when it comes to how they are going to get treated.
People act like there is some kind of important societal implication of trans-women, to which I ask, what the fuck important outcome of your gender rolls do you think you are performing as a man? Are you building fortifications? Are you dying in battle? I used to know a hot chick that killed HUNDREDS of people in Iraq with her helicopter. Are you performing masculinity better than her? What if she got shot down and rapped in a flag? Still more masculine? A few of you, sure. Most, lol, no.
There are LOTS of reasons I won't fuck a woman. She's less attractive than me. She has an illness I don't like. She is tedious. She is dangerous. She has a weird smell from a soap I don't like. She smokes. She's on drugs. She is into Nascar which I hate. Having a dick is also a no go for me, however I am not interested in women for a whole host of MUCH more petty reasons.
I think you could make a good argument that the rules regarding transwomen in women's sports are too loose in some associations. I personally don't think any transwoman should play female sports unless they went on hormone blockers and avoided male puberty. However, that doesn't mean I can't treat them like a woman in public the way I treat most women--with casual disregard.
