There should not be a barf alert on this one.
Mormonism is like being in the boy scouts to the extreme.
They are prepared for almost anything short of an armageddon asteroid, and if anyone survives, it will be them.
Your knowledge of mormonism is very incomplete.
I think the barf alert was for Romney, not the Mormons.
The barf alert is because it portrays Mormons as being holier than anyone else. Of course, Mormons have to believe and promote this viewpoint because they are a religion of works, not grace. That is, you only get your planet to be God over if you accumulate enough good works - so if Mormons aren't outproducing on the good-works quota meter that implies they aren't the chosen ones.
This also goes to why Romney should not be president based on his Mormonism (this always gets me labeled a bigot, so what). Romneycare is a good works kind of program that mimics the Mormon social structure. It also is exactly Obamacare, which is a political and economic abomination.
Thus Romney's Mormonism is directly related to how he would govern, which is not conservative but paternalistic quasi-socialism. Romney is not a classless Mormon, but an upper class Melchizedek priest who was both a Bishop and a Stake President - he is a man on a mission to Godhood and obtaining his own planet.
People need to really think five times before getting the conservative movement wrapped up in this whirlpool of theocratic mumbo-jumbo which hangs from Romney like a thick moss. I've seen lots of this stuff here in Mormon Las Vegas, it can get pretty darn weird.
I think they're actually even prepped for asteroids.
