Apparently,
Mormons are well aware of these sentiments.
Years ago I worked
in an Embassy where my boss was a Mormon. He told me that as part of missionary training, Mormons are required to go door-to-door for a time, spreading the “Truth”. When he was doing this, he would ring people's doorbells and if they seemed receptive, would
go into his speech; if they responded unfavorably, he would always wave his hands in the air, back off, and say, "It's
okay, it's okay, I'm a Jehovah's Witness" and walk away.
Was he pulling my leg? No, though he laughed about this when he told me about it. He'd come very close to being punched out on his second or third expedition. He really didn't like making people mad, didn't like missionary work either, so he found what was for him a humorous way of ending an argument.
I remember wondering just how many of the Jehovah's Witnesses I’d encountered were actually Mormons.
