A bit later in the exchange, Buchanan slammed Maddow for being 'out of touch' and seemed to slam judges who support affirmative action when he stated, "You know what they ought to do? They ought to defend the rights of white working-class folks."
Maddow, who kept her cool throughout the entire exchange cut him off at that point and snapped, "I don't need a lecture from you... a lot of things divide us Pat, for you to privilege race and say that what we really need to do is make sure that we tap into white people's racial grievances, you're dating yourself and playing with fire."
More to the point, so the hell what? White people did these things because they intentionally excluded people of color. And not because these things were something only whites could conceive of and execute.
In particular, African Americans were mostly in chains during the American Revolution and Civil War, and the Army was segregated during WW II. Suggesting that whites were great because they benefited from being slave-owners and segregationists is the height of stupidity. It's about like saying Hitler made the trains run on time.
(And yes, I'm bringing Hitler into the debate intentionally. Too bad if you don't like it. In this case it's an apt comparison.)
Moreover, whites conquered the 2/3 of the country still controlled by Indians and the 1/3 controlled by Mexicans. I guess that explains why Indians and Latinos couldn't provide too much help in "building" the country. They were too busy dying in white wars of aggression.
We could go on and on about this. 100% of the US was owned by indigenous people before whites stole it. 100% of the Europeans who came to America were aided directly or indirectly by these people. 100% of the adult Americans in the country's first two centuries were complicit in its genocidal policies against these people. Etc.
Amazing that Buchanan is what passes for a right-wing pundit these days. A child could outdebate him and his kindergarten-level argument.
For Buchanan's previous bouts of racism, see:
Sotomayor practices "tribal justice"?
American patriots have same DNA?
Mestizo leaders = "scrub stock"?
Buchanan: Helping Indians = "pigout"
