there are actual Nazis out there who want to put people in ovens, so it's taboo to make jokes about how they may have a point.
similar thing with trans people, you mention them and trolls come out of the woodwork saying they should kill themselves.
there are a lot of horrible people and trollish behaviors online, and sometimes the only way to deal is to avoid the topic that brings it out, which kind of aligns with the objectives the trolls wanted in the first place. social media isn't making these calls as some kind of woke social engineering, they're making them to avoid a death spiral into a cesspool that destroys their business and civil society itself. Yeah, it's silly to read "AI comic canceled for transphobia", but maybe it's not just the community standards that are the issue.
