Was "The Old Man" an Atheist?
2 points to consider:
1. In the beginning of the movie Ralphie's narration says, "Some men were Catholic, others Baptist. My father was an Oldsmobile man." Seems specific to mention religion as a comparison there.
2. It's never even implied that they went to Church, as evidenced by their late night Christmas Eve at the mall, and the next morning when the kids wake up and then the old man reads his funnies all day until they go out to eat.
What say you?
