I could make a game that has a police officers that allow you to murder them in broad daylight in public... and the fact that I CAN do it doesn't protect me from scrutiny for making that design decision. It's a pretty stupid decision... regardless of whether or not "it's just a game", which is why "it's just a game" is not a valid counter-argument. It's just dismissive... in which case, why even bother trying to argue?
