@SYnapse,
"The point stands that if everyone adopts my way of thinking there will be no war, and if everyone adopts Octavious's there will be war, therefore mine is the better perspective."
Actually, there is an important logical gap here. There is a missing premise, namely, "There is a peaceful way to reach a point where everybody has SYnapse's perspective."
But there's not. So yours is not a better perspective in this, the real world. Particularly because, if the good people adopt your perpsective, and the rest don't, then the bad people take over and utterly oppress the bad. So while we're being consequentialist (which we apparently are now?), let's go ahead and not let those 6 million Jews be slaughtered, mmmk?
So you're right. If everywhere is called Nazi Germany, then there wouldn't be wars between countries. And there might not be too many people slaughtered anymore, since all the Jews, principled Christians, homosexuals, Muslims, etc. might already have been killed off. But I admit that this seems like a worse world. If we're being consequentialist, then I'm going to say we should not live in the world where millions of people are slaughtered by their own state, and the rest live in permanent oppression. And if we're being moral objectivists, I'm going to say that right is toothless unless we can stand up and stop those who are perpetrating evil, and that their right to life ends when they flip the switch on the gas chambers.
