Even excommunicated LDS are not shunned unless they actually did something so offensive to their family that they couldn't bear to be in the same room with them. JWs often don't even know why they are shunning someone other than the elders said so. Seriously?
And day to day life of a Mormon is actually a lot more normal and inclusive and (dare I say) pleasant. There is a sense of theirs being the 'true faith', but it isn't an overbearing self righteous infestation there so much from what I observed. They have a heirarchy system for sure, but while the doctrine was different from other churches, the basics about living a Christian life (being worthy) were much more standard and the (rich) church actually has extensive charitable outreaches as well as evangelistic. The thing is, the charitable works are funded more by their tithes/offerings and the evangelistic are mostly funded directly by those on the missions (missionaries support themselves with help from their personal families and friends). There is definitely a strong American work ethic structured into LDS teachings, as well as encouragement to be educated and involved in community. This is the opposite of WT values.
