First off, I don't see any evidence of "knee jerk" anything. All those who made criticisms offered limited, specific critiques with supporting evidence. Just as importantly no one ever said. . .whatever it is you just tried to express. The question is whether the US ever did anything wrong in entirety of World War II. Captain America claimed that everything that was done by the Allies (or at least the US) in that war "made people more free." We took issue with that, and thereby worked several people into lather, because god-forbid anyone ever criticize the United States in any way about anything at all.
