I'd say that Popper's Paraphrase isn't a useful argument when it reduces to just a first-accusers advantage. It's a small mercy that he died before seeing what his work would be reduced to.

Tolerance is meaningful when it is mostly unbearable, otherwise it's just preference. That idea is elaborated well in SSC's "I can tolerate anything but the outgroup." The relative truth of wrong information is a glass house I don't think advocates of censorship are intellectually equipped to defend. Their only tool is deception, and inevitably force, and the points we can score on them have no value.

The deeper controversy is whether on the internet we will accept a rules based order, or discretion. It's the old "rule of law vs. rule of men" issue. What has changed in the last 140 years or so is of course, total, instant globalization, with the internet, but more subtly, that the language used to reason about these things has itself become unmoored.

What I think we should all reflect on is how as individuals we can become a bit less enthusiasitically murderable to one another, before worrying about how we can change what others think. It's the one problem we can all make progress on.
