One thing that's tough for people who just join the Fediverse, like most of the folks on #theforkiverse , is that there are self-appointed experts who reply to their public posts saying that "the Fediverse" doesn't like that kind of content.

This is untrue. They don't speak for all of us. Nobody does. You can't spell "Fediverse" without "diverse"; for good or ill, there are different viewpoints on almost any topic found here.
