I'm suggesting to our non-American friends here that they should look inward and clean up their own act before castigating America with their holier-than-thou attitudes.
Alan's response is the essence of whataboutism.
"Whataboutism, also known as whataboutery, is a variant of the tu quoque logical fallacy that attempts to discredit an opponent's position by charging them with hypocrisy without directly refuting or disproving their argument."
It is a subterfuge to change the subject away from something he does not want to talk about.
Not to mention that "castigating" is a gross overstatement and no one expressed a "holier-than-thou attitude".
So overall a failing grade.
