“We brought it up early and often. It was mentioned in the first session and as a troubling trend in our society, and an indication that we have to deal with issues of discrimination or potential discrimination. And these are issues very much being debated in our own society,” Assistant Secretary of State for Democracy Human Rights and Labor Michael Posner, who led the US delegation to the talks, told reporters on Friday.Even if the lies about the AZ law being about racial discrimination were true I find it difficult to compare that with almost anything China does.
Maybe Michael Posner should pack up and move to China and see how he likes it. Hey Mikey, if you do go, make sure you don't go in as an illegal immigrant. You might find out what serious human rights violations are like.
