The point of Reformation was a rejection of the Catholic lines of thinking....like you couldn't understand the Bible you read (even if it were in the vernacular) and the too much thinking was done by one man - the Pope.
That's a complete caricature, and besides, I don't think Protestant beliefs about the Perspicuity of the Scriptures (and its corollary, that if two people disagree on how to interpret the Bible at least one of them must be stupid and/or evil) are likely to promote more religious freedom.
