The mainline stance on Darwinism on the left has been a rigid stance that is almost impossible to break. The list goes on of issues that are stuck in the last century, or before. It might be useful to simply not take a position on evolution (theory) on the left, apart from a general statement about the reality of evolution. Darwinism should be set aside in favor of a nervous realization that any position is going to be wrong.
Let me repeat: science, religion, and academia can’t get the issue straight, yet try to impose dogmas on the public. All of them are wrong.
