How did roger Williams challenge puritan leaders?

Roger Williams challenged Puritan leaders by advocating for the separation of church and state, arguing that government should not interfere in religious matters. He believed in the importance of individual conscience and the right to worship freely, which contrasted sharply with the Puritans' belief in a unified church and state. Additionally, his criticism of their treatment of Native Americans and insistence on fair dealings further antagonized the Puritan leadership, ultimately leading to his banishment from the Massachusetts Bay Colony. Williams went on to establish Rhode Island as a refuge for religious dissenters.
