I think I posted this elsewhere yesterday on another thread, but it fits well here too.   I was sitting in a hospital lobby...a man in his mid/late sixties was going around and very aggressively wishing passersby Merry Christmas, if they responded back with Happy Holiday, he would become very in your face and insist that you say Merry Christmas. Then he would start preaching at them. I was halfway hoping a militant atheist would come along...
