In a feat of censorship worthy of a crazy, conservative, right-wing government the Alberta Liquor and Gaming Commission has banned the Monsters of Schlock!, a stunt/comedy show with some "extreme" content from a bar in Grand Prairie. I found the press release at ModBlog, the best body modification blog ever(NSFW).
The ALGC shut the show down the show using a law that allows complaints about "Entertainment that has the potential to be considered bizarre, grotesque or offensive" to be referred for approval to the commission. In this case the bar was informed of the commission's decision to ban the show at 4:30pm the night of the show, which had been well advertised and was sold out.
According to the press release I linked to above this show has been performed across Canada "to thousands of satisfied viewers" with little complaint. Most people who are interested in a show like this are going to be forewarned that it is not for the squeamish. Since the show was booked to perform at a bar I would assume that everyone who planned to be in attendance was an adult, capable of determining if something was too "bizarre, grotesque or offensive" on their own.
We don't need to state to censor events that are clearly meant for certain audiences. I highly doubt that anyone who bought tickets to this show would have been offended by the content, they may have been a little squicked-out but that's part of the reason for going to these shows. People who are easily offended have the option of not purchasing tickets for shows they might find offensive.
The state has not right to be the morality police. Our rights are not violated by events that we have the option of not attending. If the show were performed in a very public place, such as on the steps of the legislature, then the government has a duty to intervene. In this case consenting adults who were undoubtedly aware of the potential for the grotesque hard the right to see this show and the government had no right to shut this show down.
