Just enjoy the Generic Winter Holiday Season in your own way, and let the wave of the media wash over you. If you get too much on you, just wash it off or hand it to your Gentile friends, they'll appreciate the ecumenical cheer.

Personally, I look at the decorations as an embellishment of Yule, the celebration of Winter Solstice usurped by Christianity to increase church attendance. Then I look at Lucy Van Pelt's point of view and celebrate the Gift Getting Season!

And Kwanzaa... no.
