Lol that’s just blatantly false…
Patrick Henry tried to pass legislation in Virginia imposing a tax to be paid to church ministers, with the tax payer deciding which sect of Christianity his taxes went to.
This was opposed vehemently by James Madison, and instead legislation written by Thomas Jefferson in 1777 called the Virginia Statute for Religious Freedom was passed. Jefferson described the purpose of the bill as protecting “the Jew and the Gentile, the Christian and the Mahometan, the Hindoo, and infidel of every denomination."
both can be kinda be true imo, op still wrong. the founding fathers made their religious freedom legislation broad enough to cover all religions, while at the same time they likely never dreamed of a day where Christianity wouldn't be the dominate religion in America. Let alone America becoming a secular society overall.
But people like the OP cannot be convinced that the USA wasn't founded as a religion nation. And it wasn't. Were are not a theocracy, and never were, nor were we ever supposed to be. The founders were inspired by the enlightenment, and disliked the relationship between the church and monarchy. The wanted religion out of government, even if they weren't anti-religion. The move to make a separation between church and state supersedes all idea that any single founder had about which religion was the correct one or which should be the predominate one in America.
