Google -- Don't Blame Us, Blame Racist Internet for White House, 'N***a House' Mistake

Google finally got to the bottom of that whole "n***a house" map search screw up, and it says the culprit is none other than YOU ... if you're a racist who frequently uses those words on the Internet.

Here's the explanation from a Google spokesperson, "Our ranking systems are designed to return results that match a person's query. For Maps, this means using content about businesses and other public places from across the web."

In non-egghead speak -- Google Maps matches searches for "White House" with words commonly used when people discuss the White House in public Internet discussions.

If their logic is accurate ... there are a ton of web users calling President Obama's residence the "n***a house." Sad to say ... that's probably true.
