How perfectly asinine.
Everything that is termed "art" can be said to "make a statement." S'what? Are you making the grand suggestion that all "statements" are of equal importance? And who says Marshall Mathers of all people is a credible messenger of issues "Amurika" needs to "confront"? Of what worth is a "statement" that is wrapped inside a medium so offensive that the allegedly important point is lost in the controversy?
All deliberately offensive entertainers and "artists" have already said what you have written. Madonna, Howard Stern, Marilyn Manson, Ozzy Osbourne, Trent Reznor, Eminem, take your pick -- they go out of their way to become parents' worst nightmares, and then they whine, "I'm so misunderstood!"
Congratulations on being a human parrot.
