You clearly reject the notion of free speech on the grounds that some people tell lies. This is highly inconsistent, because the notion of truth is abstract and certain notions, although obnoxious, are not necessarily "untrue" in a factual sense.
So when Ulster protestants in the 70s claimed the Pope to be a "Satanic Anti-Christ", it was just as true (according to their belief system) as saying he wasn't (in accord with a differing belief system).
Maybe you can elaborate on cases where lies and truths are less obvious?
All the very beasties.
