First graders debate?
My 1st thought also. IMO that was just an excuse to try to get it stopped because the “teacher” didn’t like it.
My four year old grandson, a christian school pre kindergartner, has some intriguing conversations about God and heaven. The latest is how can goldfish go to heaven if they get flushed in the potty when they die. Not a deep theological discussion, but a discussion none the less.
That's the teacher's viewpoint. You have to consider that most liberals can only debate on this level.
