Okay I broke down and read this thread. I admit I am not LDS, I am a non-denominational Christian, however. Having said that, I have business partners and friends that are LDS. I admit that I don't share the same spiritual beliefs, I even believe some of what they believe is downright kooky. They are, however, some of the most respected people I know. Some of the most 'deserving' of eternal life.
I have not felt compelled by God to attempt to have them denounce their religion, but if I did, I'm quite certain God wouldn't direct me to do so by attacking their spiritual belief system on an internet sports message board. I would urge you, OP, to inquire with your pastor as to whether your actions here are in line with your doctrine, whatever it may be.
