Yep. "I disapprove of what you say, but I will defend to the death your right to say it." and similar such sentiments.
One can publicly declare a speaker to be a wrongheaded pig that all decent people should ignore, but that's a wholly different thing from ensuring that said pig is unable to utter its wrongheaded ideas in public.
But the question is, if the speaker of vile speech is being persecuted by the powers that be, will said brave "free speech absolutist" NGOs step up or will they be conspicuously absent?
