While there is plenty of anti-American sentiment in the Middle East, and it relates to protests, I'm not sure that has so much to do with the destruction of the embassy and the murder of the Libyans and Americans there.
I don't think that the President being seen to support deliberate antagonism of deep religious prejudices (by parties interested in more and worse war) will help.
You don't see the President publicly supporting strident anti-semitism or holocaust denialism or racism or eugenics, either - though those are taboos for western society more than for predominantly Muslim societies; consider how much Ahmedinejad's casual holocaust denial has done to maintain anger about Iran in the West.
