Evolutionary biologist, Jerry Coyne, gives an example of the process in his Blog of 20131013:
“Most Orthodox Jews reject evolution. At TAM this year, I met two ex-Orthodox Jews who had been brought up to reject evolution and, in both cases, studied the subject to be able to attack it more effectively. And in both cases they became convinced of evolution’s truth, which undermined their faith, and then left the religion.”
