: "They are controversial statements" According to who? The sources don't call them controversial statements (WP:STICKTOSOURCE). They are not debating the film. "Fuck these bitches [for not featuring me in the movie]" is, in fact, a critical assessment, as would be something along the lines of "this film is amazing" or "the film was good but I dislike such and such about it". I strongly suggest you look up the definition of "controversy"..

 :Unless you can prove that Heller or MC Ren's statements have sparked some form of controversy, they should not be referred to as one. (WP:NOR) As it is, even the "violence on set" section should barely constitute a "controversy".
