the sane response is to go “wow that is awful. the gaming community does indeed contain some terrible people, i am glad to be one of the good ones and will distance myself from this behavior”
I'd say the saner response is none at all. This seems like a pretty niche community issue somewhere on the internet involving at most <100 people. I doubt anyone here is closer then 3 degrees of separation from anyone involved. Why would you expect any of the outsiders here to "take a stand," based on incomplete information?
On here I'd 100% agree, though if some member here got into some kind of discord drama that you weren't apart of, why would you choose a side? You'll have incomplete information, and no doubt one of them will claim they were harassed while leaving out some important details.
