You can't speak nicely about politics because politics is the human dynamic. When you perceive humans are working well together, politics is great, and when they are not, politics is immoral. Since there are sides that are vying for control and attempting to shape the way things are viewed, there will be battles, and our positions and alliances will harden us.
Politics has now become a religion. An example: for one side, it is always moral air on the side of high taxes. And for the other, the principle is to cut it as often as you can. Sometimes either side puts the principle ahead of people, and people then suffer because of it.
It is becoming a religion on the Right, especially amongst libertarians, Neocons, and absolutists of any sort. The same is true of the left, but the left has been religious pre-Marx. Dogma's, such as the wealthy or our military are inherently immoral are thrown around liberally have been echoed through the ages.
