I remember a rally a while back...I'll find a link here in a second...where Obama had a rowdy group of young black men in the audience. These guys were pressing Obama to "stand up" for black Americans.
Obama calmly allowed them to say their piece and then said (and this is from memory - google hasn't provided the link yet) "There is not a black America and a white America...there is a United States of America." He went on to say that if they didn't like that, they shouldn't vote for him.
Several times - including once that I witnessed personally - Obama has stopped speaking and directly addressed the crowd. Sometimes, he asks them to stop incendiary remarks; other times he addresses their concerns.
Okay, just found a link. It's a blog, so I can't vouche for the opinion content, but it has two Youtube links of the instance I'm refering to. My computer's slow, though, I'm left assuming the links actually show what the blogger says they show - the encounter between Obama and the rather upset young men.

It bothers me that Palin didn't address what was being said at her rally, and in fact, she kept on smiling and kept on building the tension. Were her remarks intended to bring on such a reaction? We can't be sure, but we can hope not. But even if you assume that that wasn't the intent, she damn sure could have said something when things swung in that rather ugly direction.
On a seperate note, we apparently have some pretty strong feelings about people yelling things like "terrorist" and "n*gg*r" - and rightfully so, IMO. We disagree at how much blame can be placed on Palin for the things that happened at her rally, but that doesn't make the people on either side of that issue rascist.
