So they want Santa to say "ha, ha, ha" instead of "Ho, Ho, Ho?" That sounds a heck of a lot scarier, kinda like something an evil mad scientist might say. If not that, it makes Santa sound like a fool.
If the PC folks are sincere, guess they'll be going after pirates next. They say Yo, HO, HO and a bottle of rum. But probably not. PC only goes after and tries to change traditional Western values and definitions of words. What could be more traditional (and safer to mess with) than Santa Clause?
Any Santa who says "ha, ha, ha" deserves a bag of coal.
