Natural selection within the human species is still happening. Natural selection or survival of the fittest, for the human species, means in this day and age that the most technologically advanced armies will defeat less advanced armies. In short, natural selection is a war, a war to capture and consume natural resources before some other members of the species do.
Your sentiments here are decent. And it is not important to quibble what we call the selection.
Science does not study what to call things, but rather how things behave. In our time, human influences cause Selection by acting along very, very, very, very (got your attention?), very different pathways than Natural Selection operated for over a billion years. That is a reason to consider calling this Selection by some other name than "Natural." Whether it is called "Artificial" or some other name, the point is to notice that Earth is being transformed by the consequences of abstract plans, news and disinformation, and groups of persons refusing to use their ability to think.
This is not the usual pathway of Natural Selection by a long shot. Instead of time and chance gradually sorting genes over thousands of generations, we are approaching a showdown at High Noon with our own species-wide ignorance likely to get in the best shot...in one or a handful of generations, and not by time and chance but by sheer meanness of spirit and loathing of the opportunities our billions of human minds could have accepted.
The wars for natural resources are also different from the normal pathways of Natural Selection ...in the same way.
Jesus taught the ways of peace to western society, a clear break from judiaism- to turn the other cheek and to forgive. That is the way, along with diplomacy and democracy and tolerance, to end war and achieve the spiritual state of world peace.
Natural resources and ignorance will still be issues. I am all for peace but the sanctimony of religious teachers is just the opening 1-2-3-4
of a pop tune for peace..that will really bring sustainable peace... that has yet to be written.
Jesus' lessons are deep and worthwhile and not to be abridged or summarized lightly. With love eh?
