Snow and "ho ho ho" is hardly a religious statement. If anything, this is the capitalistic "buy lots and lots of presents" version of Christmas, not the religious version.
They overlap a lot in the West especially, but they're very different phenomena. Look at Japan, where Christmas is hugely popular, Jesus is nowhere to be seen, and a poll of schoolchildren a few years back showed that most of them thought the holiday was about celebrating the birth of Santa Claus.
