So?...Just exactly what would you do? I am curious.
If a child is in a government school, he is in a secular school.
Children in godless schools will learn to think and reason godlessly at least while in the classroom. They must just to cooperate in the classroom. How could it be otherwise?
There is a solution: Begin the process of privatizing all government K-12 schooling.
I send my kid to school hoping they will focus on teaching him the basics. I don't want anyone imposing their social (or religious) beliefs on my kid.
I don't want atheist preaching (do they preach?), I don't want LGBT preaching and I don't want Christian preaching. My kid is not somebody else's social or religious putty.
I guess I'm just conservative in that I want the three R's, wood shop, PE, history, ceramics is good, and a second language is okay too. But no preaching.
That, or we could teach everybody that this Secular government nonsense is in fact an utter and complete lie. People are badly disconnected from history and what is the actual truth. Here is an example.
