I corroborated my experiences as a scientist with several other scientists/students today--including an evolutionary biology doctoral student at UCLA. None of them ever discussed the philosophical/religious aspects of evolution or science with their professors or each other. Whatever our leanings, we just don't mix science and belief.
What Rupert describes in his experiences with atheism among scientists would not happen here.
The contributions from atheists are appreciated in their writings when they can show that they understand scientific fields of inquiry.
