I see it differently. Bush showed the WTC in ads. That started it. Who'd a thunk such an expression was controversial? Then, "out of the woodwork," several people who lost loved ones on 9/11/01 (and who have been openly and organized critical of Bush in the interim) get big mass media air-time, protesting the ads.
Decent people are reserved in thier criticism. But when prodded (in this case by professional victims, pardon my expression), it is okay to show support. Showing support before being attacked would not have been appropriate.
