Speaking as someone who was vehemently against the Iraq war and lived in the US, I welcomed discrimination against my own people. The United States was responsible for war crimes in that war, and for sure we deserved sanctions, boycotts, divestment, and bad international relations due to it.
I was treated extremely rudely for being American when I went to France in late 2003, and I totally understood why. I hated my own country and my countrymen for it as well. I still do, in a sense. We owe the Iraqi people an enormous debt of reparations
