Well, as I myself know the sad history of an otherwise well-respected symbol that got tainted by a madman, I would say the Swastika is a good representation of the core issue. Even though it in itself doesn't represent anything evil, it has had an unfortunate history which has made it tainted. Would a Jew appreciate the fact that the Swastika has always been a symbol for good things?
Another example. If someone posts a message, bearing the american flag in his sig, is replied to by someone bearing the Iraqi flag, would that not offend the one bearing the american flag in some way? If I had a sig that showed the Iraqi flag in a stylized version, like that of the american flag and the Eagle, would that offend (since there is a certain feel of victory over the Eagle)?
Heck, some people around here feel insulted by the American Flag by itself (not me though, but some other Danish people get pretty upset). I know from some of the Arab immigrants, that they have some aversion against the American Flag.
What about someone who is Palestinian (dont even know if there are any here)?. If you say that you are only allowed to show National, unstylized flags, then that would prohibit them from bearing the Palestinian flag. Yet, the general feeling amongst Palestinians is that their nation is as legitimite as the Israelian one, so if someone was allowed to show an Israelian flag, it would offend the Palestinian who was not allowed to show his flag. The same can be said for a number of minorities who are fighting a struggle for independence.
I myself care not the slightest bit about Flags, I will never personally press the "report" button, I have more useful ways of spending my time (like writing long, ranting posts like this

).
Anyways, my two cents
