I don't particularly like the idea that to take a stance on one issue, someone MUST take a stand "on all issues" because it's frankly unrealistic; every person you encounter will have an "issue of utmost importance" and there's such a thing as spreading oneself too thin, and the thinner someone is spread, the less likely it becomes that they've actually taken the time to do the deep diving and personal learning required to have a "real" stance and not just a copy/paste stance off the internet.

Thaaat saaaid...

If someone has been asked for a view on a topic related to their area of expertise or experience and have chosen to not comment or even take a stance of neutrality on some ideological grounds (not wanting to engage with the wider politics, for example, which is a valid stance) then that apoliticism really has to apply across the board. You can't insist that it's important to speak up and take a stance on one topic and then turtle up when asked about another.

Even if his stance is that he thinks there's no issue at all with trans sports, if he truly believes that it's important to speak ones truth, he should say that, not "no comment".

In fact, even (as above) openly saying "this isn't something I've really looked into deeply enough to comment on, and I wouldn't want to say something based on assumptions" is a valid thing to say. If anything, I wish people would be honest and say that more often.

Total radio silence on one topic while INSISTING that people must speak up on another is hypocrisy.
