I had my kids in a Baptist school 30 years ago.
Thirty years ago, I don’t think there were any Protestant Christian high schools here in NH. Now there must be 8 or 10 and it seems like another one opens every couple years. Between that and all the home schoolers, you’d think somebody might be getting a clue but I doubt if there’s a clue bat big enough to make some of the secular humanist/NEA/board of education establishment types ever figure it out.
