"Japs" was a term used to classify all persons of Japanese descent in North America during WWII. Including American and Canadian citizens who had done nothing wrong. It is a racial slur used to degrade them. Its continued use to day is entirely to degrade them.
If you believe you can justify that because of the acts of dead people in another country, you are a disgrace to humanity.
But then, as always, there are two sets of rules in America. One for white, Anglo-saxon protestans, and one for everybody else. And if you're in the second category, you'd better hope your family's native land doesn't do something wrong, or they'll becoming up with a degrading name for you, too.
