"So, before Americans start feeling smug about how they set the standards for the rest of the world, please look in your own back yard."

That's a very tired criticism/complaint. The points made were fair and if you don't think so then argue those points. Making generalizations that Americans should not share their thoughts on injustices outside the ones our government, corporations, and/or citizens create is absurd. Which nation is without problems of their own? Does that disqualify then anyone from making any statements on human rights (as in this case)?
