Yes -- like Adult movies.
They should be banned.
No, I don't believe so. I assume that by 'regulations,' you mean that they should be subjected to more regulations than they currently are. I support the current labeling system, so that someone is aware of what they are watching. Since labeling of movie rating is already in place, there is no legitimate reason to censor things that are found offensive, since whether or not something is offensive depends entirely on one's taste. "Freedom of speech doesn't protect speech you like, it protects speech you hate," is especially applicable here. I may find a movie that has homophobic or racist sentiments offensive, but I don't wish to ban movies under that category.
I think people are going to make films, shows and music with lots more objectionable (to some) material whether we try to regulate it or not. The people who want all the sex and violence out of films should perhaps look at the society that causes the thoughts that make this film. Like, if perhaps you could walk downtown Worcester, MA without being offered heroin 10 times in a 5 block radius... with the problems in my home city I see more here and more on the screen. Perhaps, instead of taking notes about what kind of violence was on 24... you people bitching should be using that time to voluntee.
In Talley v. California (1960), the Court struck down a Los Angeles city ordinance that made it a crime to distribute anonymous pamphlets. Justice Hugo Black wrote in the majority opinion: "There can be no doubt that such an identification requirement would tend to restrict freedom to distribute information and thereby freedom of expression ... Anonymous pamphlets, leaflets, brochures and even books have played an important role in the progress of mankind." In McIntyre v. Ohio Elections Commission (1995), the Court struck down an Ohio statute that made it a crime to distribute anonymous campaign literature.
