What bias?

I know people who consider themselves centrists because they're not as far to the left as Bernie Sanders but they certainly aren't any establishment right-winger like Hillary Clinton, either.

Seriously.

One of them probably came up with this idea for a Vice story...

"To see the general level of racism in America, we took three kids from Brooklyn and sent them on a trip across the heartland, sampling typical middle-American venues along the way, such as the set of an interracial cuckold porn movie, Cliven Bundy's ranch, and an encampment of Confederate army reenactors. 

Based on our observations at these totally randomly chosen, average middle American locales, we have concluded that the heartland is still racist as f**k."
