Limbaugh a Racist? What's the real story?

Two of the most popular videos in the News & Politics category this week speak to the heated debate of late around Conservative talk show radio host, Rush Limbaugh.

Brave New Films (known for its videos attacking the right-wing, including the campaign-season hit: "John McCain's YouTube problem just became a nightmare") recently released this video, called Rush Limbaugh Is a Racist:

So - now that you've heard two sides of the story -- what do you think?
