We mostly agree, see my last paragraph. Further, "collecting" a group of scattered folks with common interests can be good even if their common interest isn't.

We mostly agree, see my last paragraph. Further, "collecting" a group of scattered folks with common interests can be good even if their common interest isn't. E.g. I know that there are "cutting" and self-harm websites, and of course the practice of self-harm is awful, but those websites may be a way to reach people and help them. As to what to regulate, I think that the anti-Holocaust denial laws in Europe make a more fraught case than anti-child pornography. Child pornography generally hurts kids even if it's not circulated. Denying the Holocaust is stupid and offensive and upsetting to many, but it doesn't harm the speaker or the listener in the same way. I don't know, one way or another, whether these laws have led to "slippery slopes".
