You're being a little fast and loose with the word "bigot." I humbly suggest you take a little more care when using it. The fact of the matter is, most of your political allies are not going to think highly of your theology. Most, however, aren't going to hold it against you and will be perfectly willing to work with you for a common cause. Labeling them as "bigots" isn't going to help that cause.
I have similar issues with conservative protestants, many of whom have an extremely low opinion of Catholicism, some going so far as to believe I worship the anti-Christ. Very few of them, however, hold that against me and are more than willing to support Catholics who share their political objectives.
While I appreciate you defining a "cult" for the less informed, defining one's worship of Jesus Christ as opposed to your specific brand and other's whom you deem worthy to be called Christians is very much indeed intolerant.
You bring up calling a spade a spade when it comes to your interpertation of what a Christian is. Yes a spade is a spade, and a bigot is a bigot.
