“So; can I infer that your family are MORMON and in Texas?”
Yes, your inference is correct. The fact that my family is Mormon living in Texas would probably lead some to the observation that it is different in Texas, because Mormons are in the minority there, but where Mormons are in the majority, that is where the clannish behavior will manifest itself. This is actually a fair point, but this sociological phenomenon is not uniquely attributable to Mormons in Utah. For example, I have a sister-in-law who grew up as a Catholic in Ireland, and became Mormon as a teen. She was then shunned by the other kids in her school, and her former best friend would not even speak to her for remainder of her years in High School. However, it would be wrong for me to extrapolate the ugly behavior by these kids in Catholic-majority Ireland to apply to Catholics generally. In fact, I would wager my life that every one of my Catholic friends would strongly condemn this ugly behavior. So I think it is equally wrong to extrapolate clannish behavior by some Mormons to Mormons generally.
There is plenty of clannishness to go around in ANY organization!
But; on the flip side:
...it is equally wrong to extrapolate NON-clannish behavior by some Mormons to Mormons generally.
