G, this is a straw man argument.
The guy in California is an atheist who objected to his daughter being forced to recite the pledge, containing "under God". One of the possible outcomes of the SCOTUS could very well be that he has no standing. He was not forced to recite, and his daughter is a Christian who says she doesn't mind the pledge as it is.
It's a silly case.
But others are not, like Judge Moore in Alabama. It was not so much his monument, but what he said. He had previously been upheld in his Ten Commandments plaque in his courtroom. But a 2-1/2 ton monument in the rotunda, combined with statements like "God's law is above secular law" and "Our laws are founded on the Ten Commandments" got it bounced.
Our secular law does not, and should not, address religious matters - if we want to protect individual rights, including freedom of religion. No one stopped Moore from doing anything in his personal life. All of his fellow Alabama Supreme Court justices, and the very Christian Alabama Attorney General, quite rightly stopped him from abusing his government position to advance a religious agenda.
While there certainly our people who reject God, this claim of God being removed from people's lives is alarmist at best.
Would you mind telling me what "Law" Roy Moore broke with his decalog? Hint: There isn't one! It's arbitary law from a judge who can't make laws according to the constitution!!
Do I need to educate you on the origins of the PHONEY doctrine of "wall of separation of church and state"? It started in 1947 (Everson Decision). Where was it for the preceding 170 years? Hint: It DIDN'T EXIST!
The greatest trick Satan ever performed was to convince the secular World that he didn't exist, and that they weren't in fact doing his bidding.
Choose this day whom you will serve.
