All the "free speech" advocates here, do you still stand by that when it comes to child porn, or specific threats against individuals? If you do, and publicly, well... at least you're consistent. If you don't then you're already ok with
some kind of censorship, and the argument is just about where the line is drawn.
I really don't like when people talk about "censorship in general" when they really mean "This is below my line for what should be censored".
If you want to make the case for no censorship at all then you need to use the most extreme examples of what will be shared and consumed because that's what will happen.
