Do you have an obnoxious relative who joins Bill O'Reilly's fictitious "war on Christmas" this time of the year? Will they just not shut up about it at the dinner table, or at any table? Do you wish there were some way you could just get them to wake the hell up, even if only a little?
You can, with this little game. Heck, you can even play this solo, if you like.
Choose any neighborhood with holiday decorations, preferably lighted displays. Note that this probably requires single-family homes in mostly-white, middle- to upper-class suburban neighborhoods--a big concession to that obnoxious relative who probably believes that that is where "normal" people live (rolleyes). Now, explore that neighborhood. It can be your neighborhood or someone else's, driving or walking (if the weather is tolerable), it doesn't matter. As a concession, let your opponent choose which neighborhood and which route to take.
Now, as you pass each residence, you keep score according to the following rules:
1. If you see any non-Christian religious symbols, you get one point. (In this game, these do NOT including those normally associated with holidays, such as Christmas trees and candy canes. Menorahs, obvious Festivus poles, even the FSM counts.)
2. Otherwise, if you see any clearly Christian symbols (Baby Jesus, angels, etc.), your opponent gets one point.
3. If the display only contains classical holiday symbols (Christmas trees, Santa Claus, snow people, etc.), nobody gets any points.
Add up your points at the end of the match and see who has more. I'll bet you rack up a lot of points, quickly. /snark
