Markos Moulitsas, the keeper of Daily Kos, has been banned from MSNBC because he hurt Joe Scarborough’s feelings.

According to Markos, MSNBC chief Phil Griffin emailed him this explanation: “I’m hoping this will be only temporary and that the situation can be resolved in a mature fashion, but until then I just don’t know how one could reasonably expect to be welcomed onto our network while publicly antagonizing one of our hosts at the same time.”

Hey, Phil, resolving this in a mature fashion would be not blacklisting someone because of a schoolyard spat via Twitter.

Realizing this will screw whatever chances I have of ever appearing on MSNBC, Joe Scarborough is an incredibly thin-skinned bully who hasn’t got the class to ignore a snarky tweet but go running to your boss to complain. Grow the hell up.
