I've noticed the same trend. Even if no one questions or faults the point(s) being made re: evolution, a vitriolic jab at religion (particularly Christianity and, to a lesser extent, Judaism) is quite common in the comments.
This is a loss. To quote Richard D. Alexander (professor of Zoology at Univ. of Michigan and an evolutionist):
"...indeed, at this moment creation is the only alternative to evolution. Not only is this worth mentioning, but a comparison of the two alternatives can be an excellent exercise in logic and reason."
