I am sorry your question is a complete non sequitor. Any parent that says they can't move out of a bad district isn't trying. A good parent will do what ever it takes, if that means homeschooling until you can move to a better district, or enrolling them in a parochial/ Christian school then that is what you do.
Several years ago my wife and I were in the process of adopting three siblings. We lived in a rural district with a very good system, but we were considering homeschooling because the principal of the high school was a complete A-Hole.
I don't completely disagree with you, but I do think it is a fair question. There are a lot of reasons that people choose not to sell their homes and move. My daughter is an example. They live in a nice neighborhood, convenient to her husband's work and many other amenities. They are not completely happy with the floor plan of the house, but they could not get a better house without moving quite a distance away from work, church, etc. They had already decided to home school their teenage son (my daughter's step-son) for other reasons when the school system redrew the lines and they went from being zoned for the "good" high school to being zoned for the "bad" high school. That just made their decision that much easier.
So I think you answered my question - yes, but you would rather move. I like the option of homeschooling because it worked for us and then my kids' school lives were not disrupted every few years by rezoning (like mine was...)
