Its just a game suck it up and deal with it. 
My god if they have a problem with it,
don't buy it. What next, will they try and pass a law to protect us from our right to choose what kind of card / video / other game we want to buy?
"Oh I am sorry sir, but the liberal politically correct left and uber religious right have passed laws protecting you from this kind of game."
I am an adult, I do not need someone to tell me what I can and cannot buy for myself. I am able to make the choice my self and do not want interferance from some politically correct liberal law maker and their holly than thou moral ethical standards force fed to me through laws that are designed to protect me from my rights.
