Disagree... Mainly because I could easily envision a society in which this argument snowballs, careening down a slippery slope until all comedy (South park, family guy, etc) is seen as harmful to society and made illegal or highly censored.
I've never played this game, but I'm guessing it is supposed to be humorous, and I think protecting satire and supporting comedic efforts is extremely important.
Don't disagree with someone because of what the slippery slope could lead to. i386 didn't argue for making any comedy illegal. i386 simply just stated his/her reasons for not supporting LSL.
There's a reason the slippery slope argument is considered a fallacy and not something that should be taken seriously in any kind of argument.
