Can you tell me the time of your interaction happened so I can look it up in the mod logs, and the thread itself? Your comment seems fairly innocuous to me, and I would certainly be surprised to see that it is viewed as a hate crime.
EDIT: I can’t see that return2ozma was actually banned in the mod log.
Returnoozma posts the same stories over and over again, to as many subs as possible, and with a clear agenda that doesn’t seem to extend much past “Biden is bad.” They have also been called out for it repeatedly by the users there, and I have personally asked them to tone down the reposts. But it’s not as if they have their content constantly removed. It was overwhelming.
If a community asks a user to ease up on posting the same content over and over, with a clear agenda, which seemed to be the case with oozma, then a ban seems appropriate.
