No, that's not what I'm getting at. I'm trying to convey a different perspective.
For example very few houses or business here have flags. It's mostly a car-dealership / cottage thing.
It's actually just jarring to see how many flags are on display in the US even without getting into political sympathies. It's the visual equivalent of someone shouting in public.
My point is that just because somebody sais something like that you should just juge him to be a nazi. Spezially if that someone just hacked some nazis.
Of course it's rude. Everyone knows that you're supposed to say "I'm happy/proud to not be an American."
