We just got back from a trip, and sure enough, they still put bibles in the hotel rooms.
I came thisclose to stealing it, because I'd like to have a copy for referencing the contradictions etc., but don't want to purchase one. It would be less intimidating to religious people than The Skeptic's Annotated Bible, which might scare off my family if I bring it around.
My dad was a Gideon, and they LOVED it when somebody took one of their bibles from motel rooms. They thought that they had saved another soul.
It isn't stealing. Next time you have a chance, check out the housekeeper's cart at the hotel/motel. You will see that they all have one or two bibles so they can replace the ones that are taken.
I do what you were thinking. I take one, mark it up with all the silly verses and the contradictory ones and then put it in the next motel room I'm in. And so is the circle of life and fun.
Here's an article about leaving thought-provoking cards inside Gideon Bibles:
Traveling for the holidays? It’s always disturbed me that U.S. hotel rooms always seem to stock a Holy Bible. Nevermind any other tradition, or say... The Englightenment. This year, I’m packing something of my own to leave behind: atheism cards! Each of these cards has a quote I think might sow a few seeds of dissent or perhaps start a long distance discourse. I plan to leave one inside the front cover of each bible I meet. Click the image below to download a printable PDF. Or make your own. There are plenty of choice quotes here and elsewhere.
