One very simple question is how offended you were when Europeans, Christians, Jews, etc. committed acts of violence and collective punishment against Iraqis, Syrians, Palestinians, etc., systemically and at large scale in the last 15 years.
If the answer is "gave no f***s", this is merely racism.
Two wrongs don't make a right.
Correct. Being angry about only one wrong, however, may make you wrong. It is exactly equivalent in that case to a false argument, if we pretend that Europeans and Americans are intrinsically better societies because we don't go to Iraq and kill Iraqis for no reason (which we did, broadly defining America and Europe).
