But you're still just saying that violence is fine as long as >50% of society approves of it. And that's being gracious, since there's no reason to actually believe that >50% of society approves of the actions of the government.
Violence is a natural and inevitable human trait, and is not necessarily wrong. There are times when it is OK, and is even the right thing to do. What better way to determine what those times are than democratically?
