Because you are afraid to say what you honestly believe

"First of all, you have to ask yourself, why is there political correctness? The only answer is because you're afraid to say what you honestly believe. Well, what a fucking shame that you can't say what you believe in America. This place stood for that at one time."

-- Kurt Russell

My comment:

Political correctness is not a species of politeness, and in fact has nothing to do with politeness or civility. Political correctness is a species of cowardice and the thirst for power.
