When I was a young teenager and "in the truth", I was talking to an elder and his wife and they offered me some hot tea. I declined and told them that I like ice tea but I do not care for hot tea. The elder told me that when I get older and find a "sister" that I fall in love with, if she likes hot tea, then I will like hot tea as well.
How little did I realize that it at the time, but he just spoke volumes about life itself, the Watchtower Org, and religion in general.
If a young man really has no interest in religion but he meets a woman of a particular faith that he falls head over heels in love with, he will fall in love with her religion as well, if for no other reason than to "get the girl".
And I have known many JW's who fall into this category including the elder who gave me the "hot tea" analogy. In fact, I truly believe that had his wife been a Mormon, then he would have become a Mormon. JW's, like many other cults and religions, are simply a bunch of lemmings.
Become a JW and you can go far! Get you a beautiful wife, often times you can marry into a good job, you can become a part of a social group. Knowing the real history of the organization is not a requirement. Just do what you are told!
