But I'm having a hard time imagining this specific example. What would be an example of political ideology from the GM that you'd want to block?
I wouldn't say I find it triggering when someone says something about men, just annoying, but I can imagine someone who is more easily upset feeling that way.
That being said, if you have friends willing to say things that they know upset you, you probably need better friends, not a card.
Examples elsewhere in this comment section like eg sexual assault I can easily see how that would both come up in a game and interact with player experience to make them uncomfortable in a way they may not want to have to explain in the middle of a session.
I’m sure the player in question wouldn’t have minded an old timey theater production of all men playing women. Drag shows are pretty modern and I’m sure entirely took them out of the setting, just as if the DM had the bad guys have Uzis and AK-47s.
