I saw one of the ads. It's the typical nonsense you can imagine. If I recall correctly, it was the verse from 1 Timothy that says a wife must submit to her husband. Then a woman comes on and says she is her own person. So come be a humanist with me!
I imagine this mostly is intended to make God-haters feel superior and enlightened. If any Christian heeds such an advertisement, it's someone with extremely weak faith. Playing on such people is simply demonic, which I believe this group is.
