I agree with every point you made.
He is mocking "birthers" because he knows it's a stupid conspiracy theory which has been entirely debunked. Or is Glenn Beck suddenly a RINO Obama supporter now?
Is Mark Levin an Obama loving RINO? Ann Coulter? Michele Malkin? Has Michelle Bachmann gone RINO?
The reason these people, and the VAST majority of prominent conservatives denounce "birthers" is because it is a ridiculous conspiracy theory. The people desperate to hang on to "birther" conspiracy theories sound just as dopey as "truthers", "Palin/Triggers", "Bush stole Ohio" cranks, etc, etc.
Every minute wasted on this whole "birther" thing is one minute taken away from doing the actual hard work of defeating Hussein and evicting his socialist butt from the White House. People like Beck, Coulter, Levin, Malkin, etc, are smart enough to realize this - and the people who continue to waste time on "birther" conspiracies are not.
