Amazing how many people are awake at 0055hrs on a Sunday morning....I firmly believe that this child attending a Christian pre-school is far more important than what her Mother happens to be involved in. I would say to Mom " You did the right thing with your daughter, can we talk about your life"? I've seen a few parents come to Christ by their children attending Vacation Bible School, maybe this "Mom" can do the same.
BTW, I'm saying this without having seen any interviews involving this Mom or the Pastor.
