You know, there is something even deeper here that is helpful to me. Watching the defense of the FLDS behaviors has given me new insight in understanding the mind of an an average LDS. Your words, “It’s not like you can be both,” are very telling of their deeper problem.
I have seen it referred to as ‘compartmentalizing’ and ‘double-think.’ On some level all (devout) LDS know that polygamy is a very real part of their current doctrine not just their past doctrine, as some claim. So when the FLDS are on trial the LDS struggle with their own thoughts and feelings about polygamy.
They try so hard to say, ‘That’s not us,’ and yet at the same time they have to admit to themselves that 100 years ago they would have been those very people being investigated by the government. I’ve watched them make mental loop-de-loops to try to come to grips with this very divisive doctrine. Just because their prophet changed the teaching, the immorality of it still won’t go away. Either their ancestors were right to practice it and the current LDS should be defending the FLDS right to practice it now, or it is wrong throughout all time.
Even if the current LDS don’t practice polygamy* in this life*, they certainly believe that it has been moral to practice and will be practiced in the next. Watching certain posters claim to have a foot in each world (Mormon, Catholic) is nearly the same as watching them try to have a foot in FLDS and LDS. Either polygamy is moral or it is immoral regardless of the times.
