Listen, I spend lots of my time on Yahoo Awnsers, defending Mormons, and trying to convince them that we aren't that bad.
I've noticed one particular pattern, non-members are always trying to find ways to justify their sins and anti-mormon/religion beliefs. It's sad to watch, but it's true.
I think this is just another way Satan is trying to decieve the public. Just like thay said that Jesus could've been walking on a submerged ice sheet, not on water.
Don't lose faith over things like this, believe me, we've yet to see the worst.
