There's only one problem with all this: the video posted by HuffPo is a fake. The three words allegedly spoken by Gibson, "bright blue scrotum", are actually in Trace Gallagher's voice. Those words were lifted from a few moments earlier and pasted over Gibson's actual sentence: "We were talking about Eric Holder today on the radio and his comment that this is a nation of cowards." But don't take our word for it. See, and hear, for yourself:
This raises the question, Why can't the left make their arguments with the truth?
Why are leftists so eager to raise the specter of racism?
Perhaps it is because they plan on using it to attack their foes regardless of factual arguments opponents of socialism.
Update: Huffpo has posted a retraction, admitting the video they quoted was a fake.
