My husband and I are very much of the opinion that getting along in society and modern civilization is a game. And then there are things we care about, too.

Regarding the quality of the teaching, there's a few things I would criticize about the quality of the teaching before her belief in angels! Given that this particular teacher and this particular school represent an optimal location in our set of possibilities, undermining the teacher's authority would most likely lead to behavior I don't want, like distrust and hostility. The teacher needs an environment with which to teach empathy, letters and shapes at this age. The religious training seems like a small thing?
