Because, to kill everyone in the USA, you would either have to come to the USA to kill everyone, or invite everyone one at a time to your small island.
But in all honesty, perhaps I didn't make my point very well.
What I was trying to say is that different cultures exist. What may be considered acceptable to a cannibal in New Guinea may very well be considered quite UNacceptable to someone from New England. Similarly, what may considered acceptable in the culture of online gaming may be considered unacceptable to the culture of the public at large.
Since in either case, the two cultures rarely come into conflict with eachother, there is no issue. In a situation where two cultures come into conflict with one another, might makes right. A good example of this is the USA vs. "Islamic" terrorists. While their culture considers the USA to be the single greatest evil on the earth, our culture considers them to be cowards who bomb innocent civilians. Who is right? Well, in this instance, the USA is, because we are the biggest, toughest country on the earth and nobody is gonna disagree with us.
