It is interesting, isn’t it? Mormons and Catholics get along just fine. Seems the people picking the fights aren’t us.
Conservative Jews are another group which gets along fine with the conservative mainstream as it uncomfortable when various Christian brands start branding others at cults because they have been such a persecuted minority they don't like seeing it done to others.
Even the Moonies, branded as a cult by many, take responsible conservative political positions. We don't have to attend their church, but we should certainly welcome them as soldiers in a common cause.
