The only reason a rating system is in place is to inform people *parents* about the content of a movie or video game. Nothing wrong with that.
But, some parents are handicapped, and allow their child to see anything they want to. This causes problems. The parents then get pissed and ruin it for everyone else. The various boards (ESRB, etc) then are forced into thinking they have to protect every single child from evil tits and vajayjays, and violence. And bad words.
Yet again, there is nothing wrong with this concept. Except it should be the PARENTS JOB. not the gov's job or ESRB's job!
