Is Santa really a harmless lie though? I mean it sets kids on the treadmill of conspicuous consumption. And when you consider the billions who live in serious poverty around the world - not to mention the millions of starving/hungry/homeless - and the concept of Santa seems somewhat offensive in the face of reality.
Maybe it's because the right-wing are crypto-fascists who view Santa as the ideological dictator who forces his subjects into slavery - after all, the elves work for free year round - and rewards the faithful with the fruits of the slaves labour and punishing those who don't toe the party line. I put it to you that Santa's workshop is actually a virtual gulag! Arbeit mach frei!
