Politicians have been calling each other liars since the birth of the Republic, but never has a Southern, confederate sympathizing representative called a black President a liar on the floor of the House. And precisely the fact that we've never had a black President until now amplifies Joe (not his real name) Wilson's tantrum. What's the answer to the question as to why we haven't had a black President until now? Racism, duh. Ignoring the historical context of a white southerner denouncing a black President in a House divided is not rational given the overwhelming history of slavery and apartheid in this country. Well over half a million Americans died in the civil war, to say nothing of the horrors of the Atlantic passage and the "peculiar institution." This is just not the same thing as booing a white President.
