That's the point, to get the people who wouldn't otherwise think to eavesdrop on a conversation that involves science.

There's no tradition of scientists knocking down the Sunday school door, telling the preacher, That might not necessarily be true. That's never happened. There're no scientists picketing outside of churches.
