And it could be wrong, I don't know what exactly happened. That's the facts as I am aware of them. If shown otherwise, I'll adapt my position. Fair is fair.
I agree, and that's the way I try to conduct myself here. So, if you can find a reputable source I can access, I could accept it.
It still wouldn't change my opinion of the 1st Amendment, though. If Congress passes a law that is found to establish religion, then that law is null and void.
In the case of publicly funded schools, the laws involved are federal school funding laws. Those should be declared null and void if it is found that they establish religion.
But that would not remove students' right to speak freely and to freely exercise religion. (That means all students not only Christians.)
IOW, the federal government should (Constitutionally) not be funding public schools at all, or have any control over them in any way, if the 1st Amendment is violated as a result.
