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.

note: conversation about Ategon's use of the word triggered edited out, might be misunderstanding, need clarified
The argument that they're using "triggered in a programming sense" is more reason to defed. What it really is is an appeal to nerd identity politics. These people revolve their identity around some lame nerd subculture, and any conflict with them turns into them thinking "wow these normies just don't understand me, a super special computer toucher!!!!!". It's insufferable whiny BS I have to deal with enough of in real life.
It's also why every "tech" community devolves into nerds whining about culture wars BS instead of actual technical discussion. They're more interested in identifying as a programmer than the actual content of programming.
This is exactly something that happens around these parts as well tbh
