The difference between a thoughtful discussion of government and political rants is accepting that others hold different opinions based on different influences or life experience. I would be foolish to try to change other people opinions, all I try to do is correct gross misinformation when I see it.
The polarization against Bush is so strong in this country that the last election was effectively run against him and not the actual candidate. I find the drum beat of Bush bashing more of a popular fashion statement than evidence of deep critical inspection, but he's a lame duck now so no longer important. I suspect the unfortunate legacy of GB is to be remembered for his Mission accomplished photo op, and ducking that shoe, while I'm not convinced that many here fully grasp the symbolic significance of that shoe event to the Arab street. The event can't be undone, but the opportunity remains for the folks in power, to demonstrate that Iraq is now a free country with a freedom of speech they didn't formerly enjoy.
I expect the new US administration to distance itself from the "image" Bush has earned in the world, while (I hope) continuing to do, what needs to be done. So far they appear to be more moderate than some supporters would like, but it's still too early to make judgments.
I remain convinced that we avoided a disaster by not withdrawing troops from Iraq a couple years ago as so many wanted. Now we have a far better chance of leaving behind a successful democracy.

PS: There's a classic story about Bill Richardson, crossing his legs and accidentally pointing the bottom of his shoe toward Saddam in a negotiation to release some US citizens back in '95. Also the Al-Rashid Hotel in Baghdad has a tile mosaic of Bush I in the lobby floor for everyone to disgrace by walking upon.
