I think women are feeling judged on their femininity by women in this discussion by the insistence that there are women who can identify every single trans male to female.
I think that because I am experiencing it. Earlier in the thread somebody says that a model is obviously a male because of the length of the neck. My neck is at least as long as that model's, possibly a tad longer. My shoulders are both broader and squarer.
I think women should stop arguing that they can tell in every instance whether someone is male or female. The fact is that they only know the ones they have spotted. They don't know how many they have been near and not realised.
I loathe the way the male to female trans lobby define being female on the basis of how someone looks, dresses and acts and I wish the women who assert that they can recognise every single male to female trans person could see the self evident point that their argument is exactly the same.
Both sides of this argument are actively demeaning women who do not present on the feminine end of the spectrum.
I also think men should stay out of women's spaces full stop and be told so. But then again I think men should not rape women, full stop, and they have already been told so. And I have absolutely no hope that either of those situations will ever be 100% achieved because as far as I can see there is no practical way of making that happen.
I also think there are four sets of trans people. Those who believe they were born in the wrong body and have felt that way all their lives. (2 sets MtoF and FtoM), those who hit problems dealing with the adult world looming at them and think not going through puberty will fix that, and the autogynophiles, who are turned on by the idea of being women.
And I think those people need treating in 3 entirely separate ways, but I have no idea how that could be made to happen.
I believe that the aggressive male to female trans lobby has done immense harm to women, gay people and trans people in this country.
