I’m going to give you a serious answer to your question.

I think Elder Christofferson was talking to (or at least believed he was addressing) those that believed in a religion but weren’t interested in putting in effort with their children and were thus using the “I’m not telling my children what to believe” line as an excuse for poor parenting.

(Interestingly, this means he was talking about the opposite of the mother who is criticizing him. After all, taking your kids to a Religious Exploration retreat would seem to me to be highly involved with imparting your beliefs and values to your children.)

Therefore, in this context, a “neutral parent” is one that just doesn’t care what values they impart to their children because they don’t care about their own moral values. (Which they hold intellectually, but ignore in practice.) Hopefully this is a really small minority of parents, almost non-existent. But certainly such parents do exist, unfortunately.

This highlights what to me is a bigger problem: our apparently very human need to choose to misunderstand those we see as “different” from ourselves. Rather than seeing the similarities between Elder Christofferson’s view and her own (which are objectively almost total), she felt the need to try to outline how she was different and what he was doing was morally bad and what she was doing was morally good.

Makes me wonder how often I do this and just don’t realize I’m doing it.

In my experience, the statement “I will not teach my children what to believe” translates to “I believe I have nothing worthwhile to teach my children.” Which may well be true.
