I was speaking more broadly of events from the past ten or fifteen years in support of left wing causes (some witnessed personally) that, for one reason or another, included some violent outbursts, in addition to the more expected vocal fury. My intent was merely to say that no side (left or right) can claim to lack a certain amount of rabidity, especially when they feel like they are being pushed against a wall. Violence isn't excusable from any side.

If you're trying to make a case for there being an equal amount of nutcase rabblerousing at Obama/Biden rallies, then you must be prepared to show some proof of this, otherwise it's merely an opinion.

The only people who are affected are people who already have a tendency toward believing what they're suggesting. (imo)

As for race, I do think that skin color is being leveraged to give more credibility to all of the rumors and innuendo swirling about Obama. Based on what I've read online in the last week, Obama is a closeted gay crack smoking communist Muslim terrorist. These accusations are empowered by an inability of too many people to give him the standard benefit of the doubt because of his “otherness”. If he were a white, Harvard educated lawyer turned US Senator named Mike Johnson, I firmly believe these sorts of slanders would not gain nearly as much traction as they have, even if all of the votes and associations were the same.
