Hmm... what about "What if there is a student that frequently has a new gender identity/preferred pronouns, what should I say to other students who might not be able to keep up with it?" Don't let them try to claim that's never a problem, there's a kid like that in my discord group(college student) that many people are sick of dealing with. I tried to phrase it in such a way that it's about the reactions of other students, not the gender-switcher. It should still make the fence sitters question, a little bit. Or even something like "I've heard students talk about TERFs or gender critical feminists, but I'm not sure what that means. Can you explain it?"

You'll likely get more response if you phrase questions like you're genuinely asking for advice on things you don't understand. At the same time, just bringing it up may raise questions or inspire other people to look into it further. So long as you phrase it like a question about recent events, you can probably slip a lot of GC ideas into the discussion subtly.
