What they get judged on is the FACT that there are NO new 'writings' to trump the old ones.
I can let Liberals slide when the want to call the Constitution a Living Document, but I have a REAL hard time when 'conservatives' treat their SCRIPTUREs as the same!
Liberals are trying to build a tyrannical government using their living document. Mormons do nothing of the kind. The comparison ends there. Let it drop; let them be.
