Guess what: not everyone finds these sorts of things offensive. If a company that was trying to appeal to a very broad audience attempted something like this, sure, they'd be crucified (and I wouldn't be surprised or find anything wrong with that outcome). But events like these target the sorts of irreverent people who enjoy this type of humor. If you don't get it or find it offensive, I'm sure they don't really care, as you aren't their target audience.
I'm getting quite tired of the idea that there isn't room in the world for things like this. Lighten up, don't be so uptight, and recognize that people's tastes are different, and events like this don't have to inherently be of harm to anyone. Hell, if you look at the main page for the SF event at Noisebridge[1], they explicitly call out a link to Noisebridge's anti-harassment policy and community standards for the event. They seem well aware of the concept of keeping the event a safe place.
