But seriously, I hope that a 35-year-old coming to an unexpected new understanding of a concrete issue with measurable consequences for many other people whom he knows personally as a result of reading extensive rational arguments might be judged a little differently than a 15-year-old's enthusiasm about a personal faith experience.

One likely difference: I don't expect my account of coming to this realization to be what changes anyone's mind. (I'd be uncomfortable if it were.) I shared it here just to illustrate that a more or less rational person can make the shift that I did. Whether you make that same transition tomorrow or ten years from now or never isn't something I can control. It depends on how well you listen, and to whom, and how well you relate to what you've heard at any given time.
