Dunno. It's my view. I've always found flag fetishism weird. It seems to me that the only reason to fly a flag in this country is to advertise something about yourself and your views.
I certainly used to feel this way, but I think the inclination to wave a flag has broadened out to non-swivel eyed loons too; people who simply want to reassert the belief that there's nothing wrong with patriotism and that they object to mass immigration.
