At its core, it's no more or less ridiculous than Christianity, Judaism, Islam, or any other religion.
the bible was written by dozens of people over many centuries - yet it is very deep and entirely cohesive. Joseph Smith, on the other hand, is a testimony of a single person, yet his stuff is weak and doesn't mesh with the bible is MANY areas.
if you can't see that difference, then this thread is useless.
Actually I could not agree with you more - in terms of
aesthetics, obviously Catholicism is superior to Mormonism. But then again, I don't think that's what you're getting at.
