They believe they are the only true Mormons as they are living true to their doctrine. Yes polygamy is still a doctrine of the LDS it is only suspended not revoked.
The polys live in and among the non poly LDS and are rarely reported because their is a double mind on this. It is still a doctrine of the church that there will be polygamy in the celestial kingdom and it just might become a observed doctrine at some point.
When, they say they are; and since my knowledge of the inner workings of either them or the main LDS organization in SLC is limited, it is beyond me to be able to make the call here.
But, the polys claim to go along with everything 'mormon' EXCEPT the marriage thing, and far be it from ME to claim that they aren't what THEY claim to be.
They make state money by making sure their wives and many kids are collecting Social Security bennies, as well as welfare and food stamps, perhaps from both states at once as they may have two houses on each side of the border (?).
Do you know?
We have an awful lot of arguments here in FRland over things that are not factual, and Joe Fridays line works for me....
