I wasn't really raised into religion - my mom was a believer (Honestly not sure if she still is, I've picked up hints that may have changed), but she never once went to or brought me to church, we never talked about religion, etc. I think she got enough of that stuff when she was a kid.
I do like to go all-out on decorating for Christmas - just last year I spent a whole lot of time setting up and coding my own tree full of individually addressable RGB LEDs, in addition to all the other decorating on the interior of the place.
Despite that I still love saying "Happy Holidays" to anyone who gets bothered by that phrase. ๐
