This is a case of “What you permit, you promote.” People focus on the 0.01% of a platform’s content that’s bad/toxic because that is what defines where the platform draws the line on what’s acceptable.
The whole point of tolerance is to say "I don't agree with that, but I respect your right to do your own thing."
This is advocating the exact opposite. Under this philosophy I can not longer be tolerant, because anything I "permit" I will be accused of promoting.
This seems like a recipe for a horrible, horrible world.
