But equally I think people like Christine Mbomba deserve an appropriate category to compete in.
You do have to recognise that the male category is appropriate. To suggest that transwomen shouldn't compete with men is kind of bigotted. Would you say gay men can compete with men?
There is a separate debate about whether they merit a special "restricted" category. You'd have to establish whether there are enough potential competitors, and even whether there is any real sporting performance disadvantage.
I've not seen any evidence that 46XY 5-ARD males have a performance disadvantage against other males. Giving them a separate category may make no more sense than having separate "white" and "black" categories. (Those are potentially justifiable - there are statistical performance differences!)
Now, maybe the only reason is the social one - that they don't want to compete with men - they think they're women, and they think women shouldn't compete with men. But that really is quite regressive. If women were male, there would be no reason to separate them. So if there are male women, having the male women compete with other males, rather than saying "no, you're the wrong sort of male" is inclusive.
But if 5-ARD males really do have a performance disadvantage against other males, and you justify it on that grounds, then a Paralympic category may be justified. But there are LOTS of genetic conditions that impair performance. Why prioritise these DSD conditions? Arguments tend to loop back to the regressive social one previously mentioned.
A Stonewall campaign of "some women are male, get over it" would be appropriate here. Drumming into people's heads that some people who are socially women - transwomen and certain DSDs - are male, and as such compete in men's events, and men and others should get over that.
