National slights, regardless of nation being slighted, aren't ok here. You've done this before, unfortunately. Would you please not do it again? It's obviously uncivil. If people can't respect each other here, they can't comment here.
Because of HN's origins, it's often the case that there's some ambiguity about whether a statement is scoped to the US or more widely. The fix for that is disambiguation, not taking or making insults.
