Yup, we had much the same experience. 2nd graders don't do shades of gray all that well.
Looking back from a bit farther down the road, I can say in the long run what they see at home has much more of a lasting impression than a few lessons at school.
So I would suggest that you don't rail about the progam to the kid. That just sends a confusing mixed message. Just talk to them about shades of gray until their eyes glaze over and then move on...
