Again, what you’re saying here is radically different than what OP is saying in the 4 points they posted. There was nothing limiting it to “on discussions about being black”.
i am demographically one of the people OP is trying to be considerate of (a black nonbinary person)–so i think i have a better idea of what they’re going for here than you. to say nothing of the fact that you’re an off-instance poster who, just to be clear for any observers, analogized the idea of paying attention to any demographic information for any reason to fascist genocides. (“Better yet we can skip that and simply put demographic badges next to people’s username, like a yellow star for Jewish people, a pink triangle for homosexuals, and… hm, that sounds familiar, where has that happened before?”)
anyways this is not interesting to me and i think we’ve established that you are one of the reasons lists like this need to exist, which is the only reason i waded in here to begin with–one of the community mods has already given you a ban for your conduct in this thread and the admins are in agreement that this should be extended sitewide.
