Hey it's great that he is proud of his heritage, anyone for that matter. It goes to show that sometimes a little common sense and courtesy to reign in such displays after being informed that everyone doesn't necessarily feel the same, especially after experiencing Imperial Japanese hospitality. The Rising Sun still carries a very negative connotation with many people who are still alive and a lot of countries that had the misfortune of being in the way of Japanese intentions in the 1930s and 40s. When it was pointed out how offensive his symbol of choice was to his co-worker, he should've shown a little maturity and consideration and removed it at least while they worked together. But he didn't, so he had to deal with the consequences of his actions. Lesson learned, move on. He's lucky that he only got his tie clipped. It could've been worse. He could've gotten the "3 Stooges treatment", which would have been much more embarrassing. I still think that what transpired was appropriate. It would've been better if it didn't happen though.
