I feel to look for perfection is a very dangerous path. More than that, it's dangerous because it doesn't exist. You can aim for it, but you already know you won't get there because it doesn't exist. Plus, I definitely think the flaws, little cracks, and accidents are a lot more interesting.
If there is a spot where you have dictatorship, where people are not free, people are not satisfied, they do not find food and shelter, they are under the poverty level, this is a dangerous spot for the whole world, because those people will move, and they will move to different places. They will be carrying bad feelings towards others.
Americans have always understood the danger of mobs. They are always dangerous; they are always demonic.
