Why do people except propaganda?

I don't care of other countries faults. I 'm not of the world I'm in America and that's what matters to me. Don't say America isn't the only country to have skeletons in its closet because that doesn't get the all mighty U.S.A. off the hook wrong is wrong and if you don't see that your ignorant. They may have polished things up a bit but the fact of the matter is unless you rid your system of all impurities it will always be the same and America cant do that, because its money and power hungry.
