Is there something in the water in district of Columbia?
Seems that they really are different in the US. In NZ if someone is of the alphabet soup variety they generally keep it very quiet, and as for parades, perhaps in Auckland but locally, not a chance.
Anyway, it's a non political issue so no mention of it in elections, that I heard.
That's not to say there are none, far from it, but they don't thrust it in everyone's face.
