Didn't Fallon Fox initially lie about her trans status in order to compete as a woman? I think there were also some nasty comments/tweets made about her opponents by her, gonna make her bleed type stuff? It's late and I could be getting her mixed up.
I remember she posted/linked a video with tests that was supposed to dismiss claims she has an unfair advantage. It showed a male and female boxer making a punch and the woman's punch registering stronger, or them punching a blindfolded man with him saying the female lunch was the hardest. But semi pro both boxers commented that both were not doing the same punch, the female was doing a much stronger one than the male (I don't know exact technical terms, but comparing uppercut to a jab) and when they looked at the exact like for like results, ( which were not shown in the vid) so when both did the same punch, the male was much more powerful.
I will try find the link in morning, but I deme red thinking, if there was no unfair advantage then you'd show male and female doing like for like.
Dh loves boxing, and goes to local matches, but he wouldn't watch a man beating up a woman, and thinks it's shocking it's allowed. However, he said he'd not be suprised if some men he's met at matches would pay even more money to watch a woman being beat up by a man.
I like the group idea, the vocal minority TA on twitter may make threats and stuff though so it's something to take into consideration. A couple of women I chat to on twitter had their personal details posted online and employer contacted for speaking about this a few months ago.
