The Obama Administration is thin-skinned when it comes to different opinions. They lock out journalists who don't grovel and toe the Obama line. This Whitehouse is worse than most recent presidents, at childishly penalizing any who has a different opinion. Different opinions are the enemy of Obama. There is no tolerance for diversity.
