It doesn't make much sense really. You say that an offensive flag is not okay, but then you say the Japanese flag is okay. How about saying that to victims of genocide in China, or people who have been occupied? Or the 'comfort' women of this country that still have a hard time being understood by the Japanese government? How can the Japanese flag not be equally as offensive to these people as the Nazi flag is to a Jew? How? Did the Nazi's all die in the war and the new flag erased the past? It was the same German people. The same Japanese people.

I reconcile that with the view that a flag is just a flag. However, you seem to be ascribing different rules to different flags. Okay, maybe Japan changed, but what about flags of occupation today? How would an Iraqi feel about a British flag? Not similar to the Nazi flag and the Japan flag? I'm not having a go, but if you don't want to offend you would have to ban a bloody lot of flags and there would be a lot less good comedy!
