This is why my own position is not settled.

Publications, preachers, performances, etc. change people’s behaviour and beliefs — if they didn’t, nobody would advertise or campaign. That change can be ‘good’ or ‘bad’ depending on your point of view.

I want the spread of harmful memes to be slowed (and, if possible, prevented), but I also ask myself “What if I’m wrong about what is harmful?” — for example, I don’t believe in the Christian god, and have seen harm done in his name, but what if he actually does exist and banning Christian memes condemns people to hell?

Or sexuality? I know people whose sexuality has been outlawed this decade in much of western Europe, as a result of campaigns by people totally convinced that their preferences are innately harmful, which side is right?

I think solving this is also an important part of safe A.I., so it would still be a very important problem for me even if I didn’t know people directly affected.
