Your question was not directed at me, and I'm not a doctor, but I think you will find the following quote interesting:
"David Brooks said he heard somone introducing Kerry at an event and they said 'This election is about the future and not something that happened in New York two years ago'. "
There are people who still have not gotten over the election of 2000 (heck, they also haven't gotten over the McCarthy hearings in the early '50s). If it is something about them, it is a big deal. On the other hand, 9/11 was something that "just happened" a long time ago that the left can dismiss -- while "lifestyle" issues like gay bishops and taxpayer-funded "art" are an obsession on the left. The left really hates Presidend Bush because he reminds people that the orgy is over and people had better grow up and think about survival. And just look at the anti-globalization riots to see "adults" having infantile temper-tantrums.
No, I couldn't say that, but they do suffer from egalitarianism where there must be equality not of opportunity but of outcome. This, too, is not a mental disorder, but IMHO it is much worse --besides providing rationale for the "envy taxes"--income and inheritance taxes --it also served as the rationale for wars waged by the communists to form a classless society. A mental disorder usually only hurts the sufferer and a few in their family, but egalitarianism harms legions and may result in the death of millions.
