Why is that? Why would a men's rugby team not be at all worried about the opposing team having a woman on it, but a women's team might be worried about playing a women's team with a man on it? Or a male jujitsu fighter not object to fighting a transman but a female fighter might object to a bout with a transwoman? It's a mystery only Scooby and the gang could solve ...
Why would a male prisoner not care about being banged up with a female born prisoner on their wing but a woman prisoner might object to a transwoman one?
Including transmen in male spaces comes at a low cost to men in terms of safety, dignity, and of fairness in sports. That's why it's less of an issue for men than it is for women.
That's why men might be more accepting (if they in fact are) of transmen. They can afford to be.
Funny though that transmen who say they are gay seem to find it very hard to find gay men willing to date them so perhaps men aren't as accepting as you imagine.
... your own quote explains why men don't much care if women are in their class for sports ffs.
Iszac Henig is a transman who switched from competing as a female swimmer to competing as a male. After being recognised as an All American outstanding swimmer as a female they are now finishing last, despite being on testosterone.

Iszac was beaten by a guy with an arm missing. This is why men don't care about transmen in their sports or spaces. It doesn't much affect them.
Back on ignore you go. Must remember to log in so I don't have to see your posts.
