I know what the thread's about because I started it, and the only purpose of the thread was to state that trans women are not women.
That's unchallengeable - they don't have a uterus or ovaries and they are not, and will never be, women.
That's it. The thread's drifted into all sorts of bollocks, which is fairly demonstrable by the fact that the same arguments have been going on for 50-something pages with no sign of consensus.
There's a thread in science about how rockets don't work in the vacuum of space. But it's also about conservation of momentum, fluid dynamics, rocket science in general, and some other issues.
You started a conversation. That doesn't mean you define it.
