How long can Christians leave their children in public schools?

As the sexual revolution picks up steam, Albert Mohler observes today ("The war for the minds of our children: New California sex education framework for public schools is a manifesto for the sexual revolution and LGBTQ movement"), "Christian parents considering all this have to understand that it raises the question district by district, state by state, as to how long Christians can leave their children in the domain of the public schools."

Because when it comes to many of the sex education and comprehensive health education programs, it turns out that parents do not even know what is being taught to their children. They are not even aware of the moral messaging that is being presented, and you can count on the fact that there are going to be an awful lot of Christian parents in California who are going to be asking how long they can leave their children in the public schools.

At this point there is still local control of the public schools in many states to the extent that it really does matter where you live, district by district, but we have to ask the question as to how long that can last, because the moral revolutionaries aren't going to be satisfied until their new moral framework becomes the curricular framework of every single public school in every single public school district coast to coast. They will not rest until that is done.
