"What a overreachingly false interpretation of the Constitution. The 1st amendment says: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;..." The Constitution makes no claims, statements, or assertions as to the "equality" of religions whatsoever."
It makes no statements regarding religion at all except to say that people may freely exercise their religion. That's equality of religion. If you are free to practice whatever form of Christianity you adhere to and the Hindu is free to practice whatever form of Hinduism, then the two religions are equal under our Constitution.
