I try to follow this myself, but I do find myself giving exceptions to specific touchy subjects. For example, I don't understand how to approach a touchy subject where open discussion actually drives away people and therefore makes it an echo chamber.
For example if a gay person left a community because people were openly discussing whether or not gay people are pedophiles and advocating for the castration and torture of gay people, and that the advocating for castration and torture of gay people wasn't being shut down, I honestly think that's a totally reasonable behavior on behalf of the gay person. And I honestly would disagree that this created anything even remotely resembling a "forward path" direction.
But, in abstract, I still believe we should openly discuss touchy subject matters. I just find myself constantly running into actual application where I disagree that openly discussing a specific matter actually benefitted anyone, and found myself agreeing that the community would be healthier if specific topics of conversation were shut down.
