The top comment there is actually really on point. "Cis" men get treated like shit in the whole intersectional TQ feminism space which dominates politically correct spaces online and in university. It's no surprise that they don't want to participate in the group which might just shit talk them the entire time they would be there.

Side note is I had a funny opposite experience at a university I attended. The official LGBT space which was run by a paid administrator turned incredibly toxic because the admin was "modernizing" everything to align with x y z national policies. What had been a fun and safe and interesting place became incredibly boring, toxic, and depressing place to be. All of the student staff who had seniority over the admin were now being driven to depression by the new admin because all the policies were being explicitly changed against the will of the student staff and members who showed up.

The one lgb group which the admin had no control over was the GSA because that was a student organization and that group would openly go against the extreme changes. The admin could and did hang job security over the heads of the staff working there so they were forced to go along with whatever the policy was. The GSA was public and openly critical of the admin in certain cases. This caused the admin to be furious that they couldn't create a unified voice with the admin as the clear point of authority. The person was obsessed with being seen as the only authority figure on LGBT+++++ issues on campus. The admin would openly and often talk about how they couldn't wait for 4 or 5 years to pass because then all the students would be graduated out of the campus and there would no longer be anyone left to remember what it was like before that person took over. At that point they could control over the GSA and the staff would stop resenting being treated like shit etc.

I don't actually know how it turned out. I only kept in touch with that center to give support to the people that were being driven into depression.
