Nowadays I'm not so sure. When 'Free Speech' is abused by a radical minority in order to corrupt a gullible and causeless public, maybe it's time to say 'No'.
The great problem is where one draws the line between what is acceptable and what isn't. I certainly wouldn't trust it to politicians or the judiciary, so who could make such decisions?
Perhaps 'public taste' should be the final arbiter, although how this would be implimented; I have no idea! What I do know, however, is that the 'public' is becoming increasingly angry about too much so-called 'Freedom-of-Speech', and if nothing is changed, that anger may well spill out onto the streets.
