Everybody's political viewpoint seems to essentially revolve around defining who the "bad guys" are and who the "good guys" are....and how to go about defending oneself against "the bad guys", who are always "the other guys". ;-) It is considered quite justifiable to commit mass murder on "bad guys"...

It's a universal form of dementia, and it leads to war, war being an exercise in which you attempt to kill the other side's "good guys" because you think they are the "bad guys", which happens to be exactly what they think about you too.

Krauthammer is, I think, a lot deeper into that form of dementia than the average person, and that makes him quite noticeable.
