I regard Mormonism as being a cult, not a form of legitimate Christianity (Mormons don’t believe in the Jesus of the Gospels, for one thing), but I think there are some parallels between Mormons and Christians, such as the over-emphasis upon marriage.
When your church makes an idol out of marriage, as Mormons and Christians do, it drives people away. Because sometimes people stay single by choice, or due to factors beyond their control.
And if you’re single in a religion that over-values marriage, there is a tendency to be ignored, set aside. Churches care more about marriage than singlehood. Churches care more about meeting the needs of married couples than they do adult singles.
There is no incentive for a single adult to remain in a church or denomination that marginalizes them constantly, or that behaves as though singleness is a disease or a second-rate life station.

We know, or can infer, some things about them from prior research. There is a correlation between certain life situations and leaving. This does not mean that being any one of these things will cause a person to leave, only that there is a relationship.
- Being single. There’s been some tantalizing research over the last two years about singles in the LDS Church.
