OP was suggesting that objecting libertarians be formed into a line
"If Texans have a way they want to do something, LET THEM, and don't live there if you don't like it."
Not if their decisions shapes text books all over the country. Not if they are receiving any Federal funding for their schools.
If they want to blur the line between church and state, and between facts and politics, then surely they won't mind the Federal Government taking away funding. After all, the Church will pick up the slack, right:)?
I have to admit though, living in an ultra-blue state (Oregon), it would be amusing to see my communities reaction to receiving a K-12 set of "Texanized" books.
It is masked but always present. I don't know who built to it. It came before the first kernel.
