"I disagree with what you say, but I will defend to the deaths of others your right to say it."

How many free speech absolutists have "skin in the game", or whatever? Every alternative to censorship suggested always puts the burden on the victimized. Like, "if you debate it in public you will defeat these bad ideas". Few who are free speech absolutists roll up their sleeves and volunteer to take the action they prescribe.

Or, you have the sophists who believe free speech is the most important thing in the world but will deny that speech has any connection to its consequences. For example, separating the white nationalist rhetoric on 8chan from the white nationalist terrorism perpetrated by 8channers.
