Please show me where the USSC has a "separation of church and state."
See the Establishment Clause of the First Amendment.
See also the Free Exercise Clause. This is especially pertinent to the Fourth Branch of government. The Establishment Clause and the Free Exercise clause exhibit a degree of balance which defines our entire system of government.
See Everson v. Board of Education
You do realize that the "separation-of-church-and-state" crowd
LOST the Everson case, right? This has been pointed out to you repeatedly, yet you continue to recite it in knee-jerk fashion, completely ignorant of what the case was about (even though it has been explained to you again and again).
See Lemon v. Kurtzmann
Ah, the Lemon test. Now you're getting somewhere. The Court ruled that the Commonwealth of Pennsylvania could not subsidize the salaries of Catholic school teachers even though there was
ZERO Constitutional prohibition against it. Once again, your position is at odds with what the Constitution actually says (in contrast with what you wish it said).
Of course there is also Lamb's Chapel v. Center Moriches Union Free School District as well as Good News Club v. Milford Central School. In both of these cases, the High Court ruled that the Establishment Clause could not be used for the purpose of viewpoint discrimination, which is exactly what you are doing. Maybe you should do some research and learn a few things before blindly offering up liberal talking points. I get a big chuckle every time you mention Everson.
