I agree with the underlined. But how is a comic meant to predict that an offensive joke can have that kind of impact? That level of foresight is quite unrealistic. Best thing they can do is to stop performing jokes that has been twisted by bigots.
Free speech laws can also be used against those at risk. There was a couple cases in the UK. A brown female activist dropping a tongue in cheek hashtag that said 'killallwhitemen' got into serious trouble. There were also two black rappers that may get sent to prison for a diss song.
I don't think it's that unrealistic. Even in the 80s Comedians could have done better when it can to homosexuality. I'm think Eddie Murphy stand up about being terrified a gay guy would rape him. Those sort of jokes age poorly, but if you ever actually thought about the joke, you could tell that at least on some level, he saw gay people as predators. That sort of joke only normalised the opinions of those who already thought this. There was no deconstruction of this opinion, it was validation.
I'm going to add that laws that restrict free speech are to typically protect at risk groups. That said I'm also for hate speech laws. Just because one group is seen as protected shouldn't invalidate them from prosecution under hate speech laws. I'd need to know more about the examples before going any further, but in general that what I believe.
