I teach a seminar on science and religion. The greatest challenges are 1)to budge the assumption that the two are forever at odds; and 2) to coax students to talk about their beliefs.
The second is the harder. The idea that religious ideas can be as worthy or respectable as scientific propositions is foreign, even among those who attended religious secondary schools.
Their reluctance to speak of personal beliefs reflect the culture's tendency to confine religion to private life, apart from public, intellectual discussion. It's also rooted in the common notion that talking about one's religion constitutes an attempt to "force" convictions on another.
It is cool, however, to be anti-religion. The zeitgeist seems to have made it respectable to declare atheism. To a large degree, this is typical questioning of indoctrinated religion, and a healthy one. But I think there has been a stronger presumption against religion based on no early training.
None of this is a criticism of students. They have imbibed the culture they did not make. And they're a wonderful group.
