Vinshine is a company located in Asia. Telling its owner that you were raised by vets who fought in Asia (Vietnam, Korea) is not necessarily going to prove to them that you had a good upbringing. Their experience of the American military's role and mission there is, well, very different than what many Americans believe, especially those who were in the military. Not trying to litigate those wars -- excuse me, those "police actions" -- but to realize that they could see it differently might help you get the all caps button unstuck on your keyboard.
This is spot on. OP seems like one of those Americans who travels to another country and gets mad that people don’t speak English. And then speaks to them in English louder so they “understand” better.
