I've been going to evangelical churches for 50 yeats and I have never heard anybody "pounding the pulpit with anti-Mormon rhetoric." I do remember, maybe 40-45 years ago someone leading a Sunday School class about comparative "World Religions" stating that Mormonism is a most closely related to ancient Greek religion with a veneer of Christian language and which subcribes to a Judeo-Christian morality.
My pastor and the pastor of numerous churches would gladly “plead guilty” to pounding the pulpit with DOCTRINE that is exclusionist concerning classical Judeo-Christianity. If Mitt is that thin skinned he doesn’t belong in the Oval Office.
