I don't see a parallel. Discussing an event -- no matter how ignorant, slanted, or flat-out-wrong a discussion -- in a place where that discussion is common-place, like a radio station or newspaper or television news show, is not the same as bringing that sort of speech into a funeral or memorial.
Using your logic, any discussion of any event of the Iraq war would be inappropriate.
That said, the country is indeed becoming a sad place. Though, I would say it is united in its division.
