Here's a nice bit of history about religious tolerance and liberty in the colonies right in the middle of the American Revolution:
"It is difficult to overestimate the degree to which, on the eve of the Revolution, Catholics in America were still widely discriminated against. Several members of the Continental Congress, including Congregationalist Roger Sherman, were opposed to hiring Catholics to fight in the Continental Army. Only three colonies allowed Catholics to vote. They were banned from holding public office in all New England colonies save Rhode Island. New Hampshire law called for the imprisonment of all persons who refused to repudiate the pope, the mass, and transsubstantiation. New York held the DEATH PENALTY [emphasis mine] over priests who entered the colony; Virginia boasted that it would only arrest them."
In Virginia, the birthplace of the separation of church and state, it took *seven years* for Thomas Jefferson to convince the General Assembly to pass the Virginia Statute for Religious Freedom, and debates on the matter bear a striking resemblance to the sorts of thing one might read in YouTube comments.
By the time that the United States Bill of Rights was ratified, the freedom to practice any religion without fear of being barred from holding land, accessing the courts, or holding most professional jobs had been established by law in most of the British Empire.
This is not entirely surprising as many of the most influential people who formed the Federalist faction in what became the United States were in close cooperation with the Foxites in the British parliament from well before the Revolution until well after, and agreed on many -- or even most -- civil liberties and constitutional issues. The American Revolution weakened the common enemy (principally the Northites and Grenvilleites, who are all fairly called Tories in spite of their claim to the Whig mantle).
By comparison, the erosion of Tory (see above) dominance in the British parliament in the wake of the Seven Years' War led to a series of religious Relief Acts relaxing restrictions on Catholics. It's noteworthy that the first major such act, the Quebec Act 1774, was one of the "Intolerable Acts" protested by the Americans (in the political faction sense) that they argued justifed Independence. Additionally, in the thick of the Revolution, the British parliament passed the Relief Act 1778 and the Schools and Bishops Act 1782, in spite of vigorous domestic opposition (there were riots in Britain in the wake of each), and even more vigorous opposition in the parts of the Thirteen Colonies not already in full rebellion, and some upset in several of the others that ultimately did not join the American Revolution.
