Since there was a discussion of conservative vs liberals above as well at the trotting out by others of all the usual scapegoats
All that exists in reality is natural selection and evolution....
This core assumption of yours is false. However to show that to be the case is a deep philosophical discussion that would be entirely off topic in this thread.
Very briefly and borrowing the words of Bruce Charlton who is more articulate on this topic then I am.
"Most mainstream metaphysical assumptions are incoherent wrt. epistemology. As examples:
If natural selection is assumed metaphysically true, as the only and sufficient explanation of Man; then human reason must be a product of natural selection; which means that human reason can never know anything (because natural selection is about differential fitness, not about truth).
If it is assumed that the universe is assumed to be a combination of randomness and determinism; then we personally could never know this - because we personally would be a combination of randomness and determinism and could never know anything. The universe might actually Be random/ determined - but if so, we personally could never know that."
