I think there is simply an impossible-to-define line of quality/extremity over which negativity becomes incurable by exposure and where it's perfectly reasonable to ban it from one's platform. I don't think that's too controversial, but I also think that the share of people over that line is at a long-time high and increasing. Of course that opinion is more controversial, and I think is really the root of the free speech arguments. That opinion is full of subjective definitions by necessity, but I feel strongly about it.
