This is true, and I wasn't claiming anything further. However, according to Wikipedia, the United States was one of the 48 countries who voted to proclaim the Universal Declaration of Human Rights. There were 8 abstentions, but none opposed.

The Universal Declaration of Human Rights is a document which is globally accepted, therefore, to represent what human rights should be. The fact that the US, the supposed "land of the free", falls short of this, is just particularly sad.
