We want to protect freedom of speech, but it is not unlimited freedom of speech. There has always been rules around defamation, slander and libel, and in Victoria, we have effective rules on racial and religious vilification.
The only rules comedy can tolerate are those of taste, and the only limitations those of libel.
All the libel lawyers will tell you there's no libel any more, that everyone's given up.
Since neither black animosity nor the Left's falsehood of 'racial tensions' is based on the actual behavior of the vast majority of white Americans, nothing white America could do will affect either many blacks' perceptions or the leftist libel.
I've stopped caring about skeptics, but if they libel or defame me they will end up in court.
