There is a certain measure of induced sympathy that is attached with this argument.
Rating systems have been introduced on numerous occasions by different boards appointed by community leaders or they have been government sponsored. In 1985 Tiper Gore, Susan Baker and twenty other influential wives in Washington formed the Parents Music Resource Center (PMRC). The PMRC's goals are to lobby the music industry for lyrics printed on album covers; explicit album covers kept under the counter; a records ratings system that is similar to that used for films; and a ratings system for concerts. Then reassessment of contracts for those performers who engage in violence and explicit sexual behavior on stage; and a media watch by citizens and record companies that will pressure broadcasters to not air "questionable talent.".
There is a fine line between wishing for society to be aware of the messages being spewed out and beginning the fast steady road towards a totalitarian state. Dictators oppress their people in a very simple and methodical way. Their liberties are not protected by a Constitution composed by our past brilliant forefathers. With a purely speculative stance I can say that a world unfilled by diverse messages is not what any of these men envisioned when we were granted our protection from outside oppression and suppression of our rights. It is with undue need that I can safely say that we take for granted our freedoms and will only truly miss them if it is replaced with "protection".
The level that selective oppression has manifested itself on has been widespread and condensed at the same time. An eighteen year old Eric Van Hoven was suspended from Zeeland High School in Holland, Michigan, for wearing a tee shirt promoting the band Korn, even though the shirt contains no images or words save the band's name. I am hard pressed to believe that this young man posed a threat to anyone in his school due to his shirt.
