Jokes diffuse tension about difficult subjects. Although I think phrases like "you raped me" or "thats gay" aren't really jokes, those are simply offensive and stem from a lack of better vocabulary. Many kids may say these things without understanding why. But as for actual jokes, it depends. Covering all types of offensive jokes (sex, sexuality, race, age, disability, politics, rape, murder, suicide, emos, etc etc) what it really comes down too is who you say it too. And i dont even mean avoiding making black jokes around blacks. You can say black jokes around some blacks, and they'll laugh, and likewise you can say black jokes around some whites and they'll be offended. I personally do not think there is a problem with "offensive" jokes so long as they are meant to be jokes. I laugh at jokes that make fun of faults I have, even though some are very somber topics. Just know your audience before telling a joke, and ask forgivess if you offend
