A Polish Jew who is a friend of mine got to make that choice as a young man. He chose Stalin, or perhaps Stalin was chosen for him ... largely through geography. He lived then in far eastern Poland in the Russian Zoneof conquest, gained when Russia was a NAZI ally.
He was taken into a Soviet Labor Battalion and spent the war as a railroad worker, treated very harsh and cruel treatment, suffering much brutal privation. But he, and a million like him, lived! So you're right, no question of choice. Go for life.
As far as the Mormons go, we have no choice either. We take the Mormon. Whatever their strange cult is ... and it is strange ... it is American. Besides, if they get out of hand, I know we can count on the Vatican sending the Swiss Guard to rescue us.
It won't be long!
With the constantly increasing rate of Americans defecting from among it's ranks; the ignorant folks of the rest of the world have been gainly rapidly, percentage wise, of the total LDS religious organization's membership.
