Wow, yeah, and Protestantism has never, ever produced any heresies or blasphemies. (See: Mormonism, Unitarianism, "Word of Faith," all of the various errors held by the modern Episcopalians, ELCA Lutherans, etc., etc., etc.)
Sure they have. And Christians of good conscience have fled from them. The ELCA is losing members and congregations all over the place. Those that stay with the apostate group share their apostasy and judegement by not separating themselves.
