It's not "Jerusalem capital nonsense", it's good sense, you've just be deceived by the the anti-Semite nonsense. In the middle east Israel is the only democratic nation in the whole area. Please wake up. "I will bless those who bless my people and I will curse those who curse my people".
Except "separation of Church and state" is a myth and found no where in the constitution. The old saying, "If you repeat something enough times it becomes truth", is certainly at play here.
What it does say is…
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
That means that the government can't impose a religious belief or practice on you, nor can they prevent your from practicing your religion.
So, these satanists have a right to practice their religion, (albeit with consenting adults).
Most Saudis are Sunni (specifically Wahhabi), they typically hate Shia. (Iranians are mostly Shia).
