If you really think about it. In most movies nowadays there are female elves. But even so if there are no female elves, that doesn't really mean hes sexist, think about it, an elves job is grueling and hard work, if anything santa is in favor of girls.
their are about 20 sub-species of reindeer, not all of the males lose their antlers...but all of them do in fact have antlers (adult male/ adult female) it's fiction anyway, reindeer don't fly, there isn't a jolly old fat man who brings presents to children on christmas eve, he doesn't/never lived in the north pole...there may be a fat man there, but he's not santa.
He hid the female elves in his closet as personal sex slaves. Santa is a sick ----ing (literally!) man.
Well....if you think about it...SANTA isn't sexist, the companies who make the images/movies etc about Santa are because they don't include females. Oh, and btw, havn't you ever seen the old Rudolph movie? There are female elves and reindeer so yea...not every single one is only males. But yea lol.
