The main value I see in Peaceful science is that it separates the religious argument from the scientific argument. Both theist and atheist scientists reject ID/creationism because it is bad science. All too often the debate is cast in the light of a Culture War between believers and non-believers, and this simply couldn’t be farther from the truth.
Peaceful science also allows non-scientists a glimpse into the world where scientists work. There has been a lot of misinformation related to how christians are treated in the sciences, such as the movie “Expelled” that was released a few years ago. At least in my own experiences, fellow scientists really don’t care about your religious views in the vast majority of cases. There are thousands and thousands of christian biologists who deal with the implications of evolutionary theory every day, and it is a non-issue. Atheist and christian scientists work side by side with no problems.
I would hope that the take home message is that the sciences are filled with people just like those you see in your everyday life. Being a christian has as much impact on how you are treated in the sciences as it does for being a plumber or a car mechanic. The sciences aren’t some scary atheist cabal looking to take your beliefs away. Christians are a very welcome part of the scientific community, and will continue to be for as far in the future as we can see.
I think this last bit is important for one reason: we need the best scientists we can find. How many potentially great scientists have been scared away from a very rewarding career because of a distorted view of the field? I would say that there are a significant number. That needs to be fixed.
