I’ve about had enough of this “Separation of Church and State” being in my face, and being used for discrimination against Christians.
The idea is patently absurd. Having a Ten Commandments monument, if anything, discriminates against non-Christians; not having one does not discriminate against anybody.
Primarily, of course, the justice system affords due process to defendants, who have not yet been convicted and are therefore presumed innocent.
Yes, everyone does have the right to talk about or believe in God. However, this does not mean that the government needs to express a preference for religion. The government should neither express support, nor opposition for religion; it should be neutral. Sadly, the religious right equates neutrality with atheism and anti-religionism - an absolutely absurd stance.
Not necessarily. That stance has historical roots, though it's never been appropriate in the U.S. where separation of church and state has always (since the overthrow of the original Maryland and Massachusetts, and maybe Connecticut, I'm not sure, constitutions) been a principle of government.
Enforced state neutrality was in many countries born out of opposition to control of branches of the state by the church, and easily shaded off - still does, at times, especially among Islamic anti-Islamists - into hostility to religion. Just read any history of France, 1870-1945.
