Well done Beachcomber. It shows the value of hours of discussion on t'interweb!
I love Danielle Muscato, purely because when you present him to all those people who are so open minded that their brains are falling out, they reach trans peak and start putting their brains back in again.
The thing about him, is that his position is totally consistent with the TA ideology. If you genuinely believe that a woman is whatever a man says one is, then you can't argue with his assertion that he is a woman. If being a woman is a question of your inner feelings, rather than your outer body, then Danielle's inner feelings are as valid as someone who passes, like Lavern Cox and he's as much of a woman as Lavern is.
Where do you draw the line? Up to now, human beings collectively have agreed that you define what sex a human being is, by their visible biological markers (because we haven't been able to see their invisible ones - we don't know if someone is XXY, for example). There have been a handful of cases where intersex conditions have provided exceptions, but that's what they are - exceptions.
Now we are either being asked - sorry, firmly told - to draw the line at the point at which a man says he is a woman (and today it's reported that Ian Huntley, the child murderer, has decided he is one and if you believe that saying you are a woman is where the line is, then you have to accept that he is one) or we are being told there is no line at all - there's no such thing as biological sex, it's all gender fluid and feelz or non-binary (in which case what are you transing from and to?), although coincidentally, the people who were always formerly known as women, are still expected to do the childcare, make the sandwiches and suck the lady-cocks.
Hurrah for Danielle.
