I read and sometimes post to Crevo threads because I am interested in the motivations of the posters. I have stated before and still maintain that these threads have little to do with the validity of Evolutionary Biology. Real science doesn’t create this level of passion, at least amongst laymen. Real science is about study, methodical research, and peer review. It is not about forty paragraph screeds concerning why everyone should listen to the poster. People really want to post about the validity of their worldview and the need for others to accept that outlook.
Evolutionary Biology is threatening to people of faith, along with other branches of science that objectively examine the precepts they hold dear. Objective scientific inquiry has unearthed information that casts doubts upon the validity of religious institutions. This threatens not only the belief system that keeps them going, but also their position in society. If the Christian God is a myth, who cares what believers have to say on substantive issues like abortion or homosexuality?
What is at stake here is not the answer to a scientific inquiry but the justification to rule a society, the power to tell YOU how to live your days, and the ability to determine the course of a nation. The posters to these threads in their unsophisticated way are battling for the hearts and minds of a nation. That is why I am interested in these debates and why I think they are important.
Good point that it is not all about science, but worldviews. However, I think you have three worldviews in conflict: religious type, scientific type, and the arrogant/dogmatic evolutionist type. The second is extremely rare, but admirable. I fit with the 1st type myself (i am not going to pretend like I am an objective observer).
