While I agree that Umair is engaging in ignoring sombunall , at the same time you must understand that expository political writing fails to move its audience if it constantly hedges. So it probably improves the effect of the argument, though it's logically not defensible.

There is so much blame to go around that some of the rational Americans will get undeserved blame too. Your shit, your fan, when it comes down to it (if you pardon the profanity).

This is why my wife and I left the United States in late 2016. In a few months we'll be Dutch and I can finally say, "Not responsible." (I gave America over thirty years - that's long enough.)
