Re: I disapprove of what you say, but I will defend to the death your right to say it
I don't think it is anachronistic to also point out that this ideal was given an enforceable expression in the US Constitution.
(I once told a yank that this document and the Declaration of Independence "would make a really good basis for running a country". His reply was something like "So you don't think we've managed that?" to which I replied "Well, you've made a good start but it needs ongoing maintenance.".)
