Also, in all fairness, I or anyone else could punch a zillion holes in your argument. For instance, I too, as I'm sure countless other Brits, have lived and worked with foreign friends, and I too was treated with curtesy and respect. The only difference being that the folk I stayed with were not at all religious in any way -- just normal average folk with a fair sense of politeness and manners. In other words, living proof that one does not need to be a church-going type in order to respect one's fellow human being. Without wishing to sound at all negative or wishing to fall out over this, the example you gave of being treated well by one particular sect is somewhat biased. Understandably so.
Also (quote): "Most of the Mormons we will see in UK are on their 'Mission'" (unquote). Now there is the crux of the matter. Pray tell me, what is 'normal' that any child should be raised to believe that it is their mission to preach to others? Why on God's earth do some folk believe they are superior in the sense that they feel it their duty to preach their beliefs on, let's say, lesser mortals?
That said, I really do admire that your Mormon buddies are raised to be anti-drugs/anti-alcohol/anti-violence and with a semi-sence of resect for others. But (here's the biggie), a documentary on TV some two or three years ago, filming the everyday lives of Mormans in Utah over a period of several months. A bunch of Mormon teens were permitted to leave the confines of their usual lives in order to go out into the big, wide world and to experience life from another perspective. Guess what? 98% of those teens had the good sense to find a job, to avoid the undesirables (drug dealers and the like), and generally live their lives the way which THEY wanted to live - and they each made a success of it. Just 2% of those teens returned to Utah. Just two diddly per-cent. And only because they received letters from their parents threatening that they would be dismissed from their families if they did not return.
Does the words "bullied" or "brainwashed" ring any bells here?
Furthermore, the womanfolk, when interviewed in the aforementiond documentary, secretly admitted that they too longed to be given the chance of experiencing a life other than the usual hum-drum drudgery of sharing their husband with several other women. Basically, they are treated as second-class citizens, brainwashed from an early age that their only role in life is to cater to their husband's every whim.
Does that sound fair to you? One ends up questioning just what sort of people these Mormon 'men' are. Their only aim in life is to make $$$. They are driven by senseless greed, yet all the while they feel that it's perfectly normal to sleep with many wives and to treat those wives as nothing short of skivvies.
You can try to justify it until you are blue in the face, but decent, honest folk will never forget - let alone forgive - the actions of those Mormon murderers on Sept. 11th, 1857, for the very same mentality of greed and nastiness still secretly lurks in the modern-day Mormon.
My 2 cents.
