Here's a data point for you - I changed my mind because of evolution. Here we're not really interested in smart people - many smart people believe in God. We're interested in the subset of smart people with a special kind of honesty, the kind great scientists almost always have, and great philosophers often do. The 'smart people' you claim changed their minds because of fashion aren't the ones we're really interested in talking about.

Also, I like to distinguish between deliberate atheists (like myself) and people who are atheists by default. Some people are apathetic about philosophical questions and will say they don't believe in God simply because they weren't brought up with any religion.
