I don't think I really need to explain much, their admins are transphobic.

Snowe, an admin, complained about a transgender person being offended over being misgendered. Ategon made an apology post but keeps snowe on, no public apologies from snowe to the transgender people affected.

I'm not well-informed on this specific issue so I'll leave the specifics to those who are.
How to respond to unacceptable behavior is a recurring problem on all sorts of issues, though, and I think focusing on apologies is misguided. I've seen tons of insincere apologies and tons of sincere apologies that are criticized for not being enough. The priority (to me) seems like it should be stopping the behavior and addressing any damage done.
Makes sense to me, I see an apology as the smallest thing to do
I was thinking something along those lines, too -- I've seen apologies used to deflect from doing anything substantive to address the problem. "We've apologized, what do you want??"
