What were some of Roger Williams' complaints about the Massachusetts Bay Colony?

He was ahead of his time. He believed in what we have now, freedom of religion. he was a christian and believed the puritans were too intolerant but thought everyone should have the right to believe in their own god. he also supported women being able to speak in public. He believed the native peoples were being discriminated against and didn't feel it was right for the colonist to take their land.
