My beef isn't really with biologists. It isn't really even with scientists. It is with those who use evolution as a means to legitimize their belief that no God exists. They believe no God exists, because if He did, and they believed it, then the stuff that they do would make them feel guilty, and feeling guilty sucks. So they spread that around, and try to get everyone to believe what they believe, so there won't be anyone left who does believe in God who might eventually make them feel guilty.
If evolution were proven and not simply a theory, it would even make sense to me if the guiding hand of God was behind it all (if, for example, the mutations were not a result of random acts, but the work of intelligence). However, since it is a theory touted by the atheists, it doesn't look very attractive to me at all at this point.
