While I don't agree with the Baptists on much, they definately got this one right. You don't hand your kids over to the government for 7 to 8 hours a day 9 months a year, filled in various ways with sodomites, athiests and activists.
You won't trust them with your health care, but you will willingly give them your kids for most of the day? Insanity.
Unfortunately, most Baptists still think that their government schools are "different". On the other hand, many parents, and some pastors, are starting to see through the standard rationalizations. I think that the ranks of those who have given up the usual excuses are starting to grow rapidly.
