How old is the child? Does the step-mother attend with her? Why doesn't the dad exercise headship over the stepmom? Why are you so "afraid" to confront her and him on this? (Not in front of the kid, though.)
I must say that when I was a dubbie and my husband never was, he made it clear to the kids that they did not HAVE to go with me. If THEY wanted to, they could, but they didn't have to. So when they DID come, I knew it was either out of love for me (most of the time, if truth be told) or for Jehovah God.
Plenty of atheists teach their children good morals without benefit of the WTSociety or even the Bible! Actually, I'm with Crystal -- the WTS teaches half-truths and lying by omission as a way to deal with criticism and 'persecution.' THEY are immoral in their "do what we say, not as we ourselves do" management style. Two-faced is what they are. And two-faced seems to be what your friend is after having learned at their knee. I don't want to be harsh, but, please point out her hypocrisy? The child will be a BETTER PERSON for it.
FWIW
