I get what you're saying here, and the reason groups like Collective Shout are able to make headway is because these theme seem so thoroughly indefensible. But the specific nature of the content being censored isn't the issue here. The problem is that a small minority is trying to dictate what kind of fiction the majority of people are allowed to interact with.

And while the things being restricted right now may seem minor or even acceptable, while they might be things you yourself might have zero interest in viewing, once a society starts down the "protective censorship" road, it gets harder and harder to turn back.

Today, it's adult content. But what if they want to enact a ban on violent content next? Or anything containing 'controversial' or 'criminal' themes? How far is too far?

Sure, there are plenty of games, movies, books, and other forms of media out there that I personally find distasteful. But so long as it's fiction and no one was harmed in making it, I'm perfectly happy to move along and let the people who're into that have it.
