Care to elaborate? How do you protect against abuse of any exceptions in the long term? Why do you characterise absolute freedom of speech as an "ignorant" take, which could be construed as a bad-faith discussion tactic on here.
Presumably society would eventually get over itself and evolving into something more tolerant of personal opinions, and questioning internet-sourced information.
Or, from another perspective, the only alternative is that only some people can do that. (E.g. politicians, security services, etc)
I'm not sure that would be preferable.
EDIT: I mean “in addition to the government”.
