Although he may have simple meant "presume ignorance, not malice," the wording used was very derogatory.

I do not doubt that Americans on average are less educated on international affairs than other Western countries. But arguing that a factually incorrect comment about Turkish headwear on HN (by a user of unknown nationality) is a result of broader "American ignorance" is meaningless.

Furthermore, I believe m00dy's response was accurate and fair. If he viewed every incorrect comment about Turkish culture as written by an American "puppy," I doubt he would have commented, and no one would have learned anything.
