A famous brazilian stand-up comedian has made a joke in which he said that ugly women should be thankfull if they were raped, after all, the rapists would be doing them a favor - since they are ugly, rape is an opportunity for them to have sex. Many people have considered this joke to be rape apology, while many others have considered it to be an exercise in freedom of speech. My question is not about whether the joke is funny or not (well... It isn't), but wether this comedian should be in some way punished for telling it in public. What do you philosophers think? Are there limits to humour?
