Your post covers what a number of us have been saying for the last number of months, all in a nutshell.
While Mr. Romney may be a "nice guy" in the worlds eyes and may have demonstrated some business acumen, the reality is his belief in the fanciful "doctrines" of Mormonism demonstrates a tremendous lack of discernment and judgment in regard to the truth.
It is also vitally important to note that in order to obtain the high position Mr. Romney currently holds within the cult he has had to take an oath to the church; swearing his allegiance to Mormonism and its leadership and to doing everything within his power to establish the Mormon "kingdom of god" upon the earth. This fact alone disqualifies him from holding the office of President of the United States because his allegiance lies else ware.
I, along with others who have mentioned these facts concerning Mormonism are telling the truth about the cult in order to educate the public at large. To do so is not "bashing Mormonism", it is presenting reality. The facts stated above about the cult are readily available and easily verified by anyone and everyone who is willing to take the time to do some simple apologetics research with an open mind, taking Mormonism at face value, examining it's founders, leaders, doctrines and beliefs in light of history, the Word of God and the founder (The Lord Jesus Christ), leaders, doctrine and beliefs of biblical Christianity and "the faith once and for all delivered to the saints."
