Thomas Kidd of Baylor University talks about Christians wanting to sanitize the past and the restrictions on religious worship in the American colonies:

If religious liberty is one of our greatest national legacies, we can thank many early Baptists for being on the front lines of the fight for that liberty. In the Massachusetts Bay Colony, and later Rhode Island, Roger Williams was one of the first dissenting voices speaking out against a state establishment of religion, and against the state policing people’s religious beliefs. (For Williams, religion was too important for the government to meddle in it.) In the era of the Revolution, Baptists emerging from the Great Awakening wanted full freedom to create their own churches and to preach to whomever they wished. In most of the colonies, such freedom was not readily granted.

We forget that at the same time as the fight for independence from Britain, Americans were also fighting for freedom from oppressive religious laws. There were Baptist pastors being fined and even jailed for illegal preaching in Virginia in the early 1770s.
