I would posit that one can judge the quality of a faith by the way its adherents live. Whether or not Mormon theology is considered Christian, from what I can tell the way many Mormons live their lives is a lot closer to the Christian ideal than the way many Christians live theirs.
It's not a matter of lifestyle, but one of doctrine and core belief. Would you suggest that we knowingly and willfully take actions that might do harm to the Gospel? Must we throw that aside along with our conservative beliefs to achieve some political victory?
