This is one of the things you liberals do when you're logically cornered, you twist the argument into being about rights. No one here is arguing whether or not Louis CK has the right to say what he wants. No one is arguing that people do or don't have a right to criticize. We all accept that both parties have a right to their opinion and to voice it. You're shadow boxing again, but you think that you just won the championship belt.
What this discussion is about, is how liberals are now ruining comedy with their PC snowflake butthurtedness. He's always been vulgar and said offensive things. Some 10 years ago he had a bit where he said n***** (a word the left has made so vile I dare not utter it here in a PC bastion, even for simply using it as a quote). But now today's PC left falls apart from comedy. I used to lean left, but the left has gone full retard now and I have #walkedaway as you know. The left has strayed left of common sense and here we have yet another example.
