Cosmetic surgery and medication can’t and don’t change anyone’s sex. An inverted penis is not a vagina. Hormonally enlarged male breast tissue does not constitute a female breast. Thinking something about oneself doesn’t make it materially real. A male bodied person will always be a male bodied person, potentially a risk to women however he identifies, and should use male facilities or third spaces.
In this context, how female bodied people appear is irrelevant and has nothing to do with the risk to women’s safety, privacy and dignity posed by men, which is what transwomen are.
We’re way past be kind and tolerance. It more or less worked in the 60s, 70s and 80s (I know, I was there) because such situations were relatively - indeed vanishingly - rare, the individuals concerned were generally more discreet and respectful and because if a woman decided to object to having a male in a female space she could say so without being demonised. That’s not now the case.
No men in women’s spaces.
