There are probably some who have actually chosen to leave based on some doctrine on which they disagree. For example, the Catholic Church does not permit artificial contraception or in-vitro fertilization. The reasons are spelled out but, unfortunately, some Catholics simply disagree and choose to leave for those christian churches that allow such practices. Sadly, the majority of Catholics who have left did so out of ignorance. They were never properly formed in their faith and, out of ignorance, switch to some other christian church that has caught their attention.

This is very true and you are quite right to point it out. Rebelion tends to be the, mainly, a young man’s pursuit. Many may come back later as it is surprising how unimportant these things become with age and wisdom. An invite may be all some need to reconsider their position and return.
