What if there’s no chance to respond? No conversation to have? For example, speech that threatens the existence offer no chance to respond, nor conversation to establish. For either to happen your right to existence has to be recognized, but existential threats deny that. It’s not only the existence of flesh and blood at stake, but also political participation, religion, sexual identity, etc.

I agree that governmental censorship is not the solution. It has more often than not been the perpetrator. Which only leaves each individual to watch out for and stop existential threat. Which makes the absolutist standing, which from my understanding prefers waiting for such threat to finish and then responding, even more dangerous.
