Will be interesting to see if TES6 will replace Skyrim as the sort of mainstream culturally relevant icon of gaming.
After all Morrowind and Oblivion were both massively popular cornerstones of gaming in their own right in their time, but Skyrim has definitely overtaken them as fas as mainstream recognition goes.
~~Seems like a really stupid ban.~~ Unless you're overly online and/or up on the latest trans discourse in the US, calling women females is at worst a little weird, but ultimately innocuous. Could easily be an ESL issue also.
Now ~~if~~ there is good reason to believe OP is intentionally using it in the weird incelly way, sure that's bad. Although unless OP is like intentionally missgendering or otherwise harassing people with the word, I personally think it's way overkill to police it even if he does mean it in the incel type of way...
Edit: Oh wait, I'm slow. The punchline is probably that the "female" in question is either a man or trans. Yeah in that context the probability that OP is intentionally being weird is probably much higher...
