I belong to a facebook group called "That's it, I'm architecture shaming". The point is to post pictures of bizarre, unappealing examples of architecture. It nearly got shut down because people kept posting about "burning them to the ground" or "blowing them up". This causes the older and more conservative generation to become apoplectic with rants about thought police and stupidity and censorship and failure to understand a joke.
I confess, I started out thinking like that also. But the more I think about it, the more I realize that every joke, conjecture, and other expression of the idea that it is okay to burn a building down normalizes that idea. Now, the vast majority of people will be exposed to that idea and not feel any temptation toward arson. But there is also a certain limited group of people who were already contemplating burning a building to the ground. For them, might it be possible that hearing this over and over again actually does encourage them to act on that desire? And wouldn't it be better if we just always expressed disapproval when this is suggested?
Just to be very clear, I am talking about voluntary discretion and I am in no way suggesting that the government should be able to dictate this. But for facebook to be able to threaten my architecture group with a ban? I don't see why not.
