I don't claim to know many of the facts of this story but on the surface of it, I would bend over backwards to try to keep the kid in a positive Christian environment in spite of the mother. It does sound like the school has made an effort on this front as well. I just feel bad for the kid
Not every Christian school's mission is to take kids in because their parents don't like the local public school.
I homeschool to keep my kids innocent. If I wanted them to attend school with Heather, who has two mommies, Billy who has two daddies, and the local abortion provider's daughter, not to mention stripper's kids I would send them to public school. That sounds really ugly, but in fact, I want my chilren to remain innocent, with friends who share the same core values as our family. Why is it that when a bunch of families decide to operate a school, they are considered cruel for wanting the same things I want. Kids are NOT missionaries, contrary to what some think!
