The other thing is that actually Sharron's appearance is utterly irrelevant. She is a very good looking woman, but the relevant point when it comes to women's sport is that, whether she looked like a supermodel or a bag of spanners, she's biologically female. To imply that her looks have anything to do with the issue at all is misogyny, plain and simple.
And it's very revealing misogyny coming from TRAs - it shows that their whole concept of "womanhood" boils down to "looking like Barbie."
Some of the more prominent activists on twitter simultaneously seem to believe they do look like Barbie (all those pouting selfies while wearing ridiculously clinging clothes in a pornified parody of female dress), while hating themselves for not looking like Barbie - the cognitive dissonance must just about make their heads explode. Then, because of the cognitive dissonance, they project like crazy onto women: too pretty - they hate a woman for being what they are not; not pretty enough/good looking, but in a strong way - they hate a woman for being incontrovertibly a woman while not looking like Barbie.
It's all projection, all incoherent, all about holding multiple conflicting views at the same time, all about cognitive dissonance, and most especially, all about DARVO (reversing the roles of victim and offender so they transform themselves into the most oppressed people in the world - even as they engineer the most vicious twitter pile-ons and take photos of themselves with pink baseball bats).
