Saying that he won't follow orders of the Commander in Chief seems like insubordination to me. If I told my boss I didn't want to follow orders, I'd probably be fired.
Since Gary Stein started an Armed Forces tea party Facebook site, he's likely a birther. Having a black president sure did put a lot of people out of sorts. We've got half of the deep south republicans insisting Obama is a Muslim (and therefore the enemy). There seems to be a correlation between bigotry and religion, which is ironic because religious people are supposed to be moral. It seems the more religious people are, the more prejudiced they are against entire populations of people.
