If JWism wasn't forced on me by my mother, I'd never have become a JW. Had my mother given me the freedom to make my own choice regarding religion, I probably would have become Roman Catholic, since most of my close friends at school were Catholic . As things turned out after leaving the JWs I became an Episcopalian (Anglo-Catholic).
My feeling is that if JW parents gave their children the freedom to choose, most would reject JWism for another religion or no religion.
