Here’s the deal: Non-religious people are often filled with resentment for their own religion. Take a non-religious catholic. He doesn’t like Catholicism. Because he doesn’t like catholicism, he doesn’t like Christianity, EVEN if his issues might be addressed in another branch of Christianity, so if he is suddenly inspired he will either become a religious catholic, or join something completely new because he doesn’t perceive any of the faults that his first religion had. To become a baptist, for example, wouldn’t even cross his mind. The same thing happens with secular Jews as well. In the Islamic world, it gets even weirder as, in more open countries, people float back and forth very easily between the local Christianity and Islam. I have yet to fully examine it, and there definitely is resentment between the groups, but an unhappy Muslim will fairly quickly join Christianity, than something incredibly foreign like Judaism or something else.
