What is perplexing about the article is the contradictive position this mom holds. There is a reason a person sends their children to a Christian school -- to get a Christian education, learn Christian morals, etc. To then live a different lifestyle at home models just the opposite, even if the children have not been explicitly exposed to her activity, the fact that they are "ok" with it means they have knowledge of it. "Hear, O Israel: The LORD our God [is] one LORD: And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might. And these words, which I command thee this day, shall be in thine heart: And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up. And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes" (Deuteronomy 6:4-8). To teach is to demonstrate.
