I was once told by a friend of mine that the reason why she is so religiously inclined to Judaism is because she is sure that it is right and the members of other religions don't actually think their religion is true, they just say it is so that they don't have to shoulder the burden that is Orthodox Judaism. And that it is only in Judaism where members actually study their religious texts, since in other religions they know well enough to not study them too hard or they'll see all the obvious holes.
Having that come to me, a person who has spoken to many people from many religious views and who knows firsthand how seriously they take them, it astounds me that she thinks that her views are grounded in any sort of reality.
But this is after she just got back after spending the summer in the brainwashing institute which is Neve Yerushalaim and was taught by none other but the famous Lawrence Keleman (author of Permission to Believe, etc.), so I'm not totally shocked.
