I continue to wonder what is so loathsome about religion that when creationists call evolution a religion they mean it as an insult.
It's also a wonderment how they try to say they aren't saying science is a religion when they say evolution is a religion, when much of evidence for evolution comes from physics, genetics, geology, etc. I guess they think know better what is and is not science than the 99+% of scientists who consider evolution science.
They are entirely anti-science. They reject science as a method; they reject the findings of physics, astronomy, geology, chemistry — the works. When one of them asserts the sun revolves around the earth, not one of them has the guts to step in. When one of them says slavery is morally OK, not one of them has the guts to step in. When one of them says you cannot start an evolving colony of bacteria with a single organism, not one of them has the guts to step in.
They are clueless, gutless, completely ignorant of the methods and findings of the entire spectrum of science.
