I don't think what you're saying is true. I know someone who very actively doesn't want mentioning of gay people to kids. For context, he's foreign-born, isn't otherwise conservative, and has been a US citizen for probably longer than most people on Lemmy have been alive.

I mention this anecdote because it's part of many anecdotes and the vast majority of people in his community have viewpoints that I've heard and are much more extreme than his.
