Why is there such an arugument on this thread that a child's upbringing largely determines his/her choice of religion as a adult? Remember the saying, you have to be "very" religious to convert to another religion (instead of staying within your own religious upbringing).

Which is why in most cases, Protestants may go back and forth between Presbyterian, Methodist, evangelical congregations etc., but don't seriously consider becoming Catholic or Jewish unless the influence of a partner is involved.

I don't know. It's self evident, it can be demonstrated empirically, it's common wisdom, and it passes the smell test.

I suppose people will point to periods of social upheaval and forced conversions and argue that that is the norm. People with a weak grip on their own faiths are hyper-sensitive.
