So, let's say your theory of extreme global political correctness is true.
Why aren't all world leaders affected by it? Why hasn't it been consistent since day one of Obama's administration - Russia's acquiescence on Iran only came after negotiations and Israel has been actively hostile to many of his requests. Or how about Merkel's sharp criticisms of many of Obama's policy decisions?
What is so special about germany and israel that they are not afraid of being labeled racists? And why did it take negotiations for Russia to come around, after all isn't the damage done, aren't they now world-renowned racists forever to be shunned?
And why is Sarkozy so enthusiastic about the "surge" in Afghanistan but at the same time he's criticized Obama in other areas for being ill-prepared and "not always up to standard on decision-making and efficiency." How is he able to make such obviously non-PC remarks and yet at the same time has been cowed by political correctness into partnering on the war in Afghanistan? Its like he's afraid of political correctness and not afraid of it at exactly the same time.
Or maybe your theory really is nothing more than completely laughable.
