I can no longer make it through a show with a laugh track. They just spoil the flow.

While they don’t always ruin the thing, so many old shows, movies, and music have a ton of blatant racism, sexism, homophobia, etc. sprinkled in that makes it less enjoyable. South Park’s Chef Aid album has a song that is a combo of Crystal Method, Ozzy, DMX, and I think Wu Tang called Nowhere to Run. It is pretty awesome, except for DMX inserting a few homophobic lines. That asshole ruined a great song!

Overall I notice mean jokes and cruel humor, which is still around to some extent but far less often without the person making the joke clearly an asshole. Stuff like Mel Brooks that included some humor about groups that were frequently mocked, but in a way that is mostly self aware parody, aged pretty well.
