Well of course it is being unable to articulate a position opposing President Obama without exposing themselves as the racists they are. I would argue that more than anything they just can't believe that an African American male is president. It really is about race and purity. They look around America and see that it is changing. It is obvious to them that the mixing of the races has led to the pure white male literally loosing dominance and therefore power.
Today we have a piece in the Washington Post that brings another group or association joining their ranks that should embarrass them, North Korea. A blogger named Josh Stanton found an article in the Korean Central News Agency regarding President Obama. The article in the Washington Post mentions the point that the insular views in North Korea have frequently revolved around race, using the example of supporting Japan in WWII.
Daily Kos members will recognize the language from previous American conservatives, usually with an update that "if anyone was offended " they apologize. Really the only thing their comments mean is that they resent and hate President Obama. Here are some quotes from their new best friend.
President Obama, "is a crossbreed with unclear blood ", "does not even have the basic appearance of a human being " and is the "[F]figure of a monkey while human race has evolved through millions of years ". (Please note that there may be some problem with the last comment in that it appears to show a belief in evolution)

When your fellow thinkers are the like of the KKK and North Korea it might be time to reevaluate your associates. In their case all it shows is the lack of their ability to win their arguments on the merits and therefore descending into the refuge of tyrants and racists.
