I am not eager to jump to conclusions about such sociological questions, but let me guess that in general the public is fed up with reductionist Darwinism. Now it may be that the center of gravity of this feeling is religion, and the induced efforts to promote religious tradition. But, whatever the case, the confusion created by Darwinism makes people resist.
I am a science fan, but a Darwin critic who thinks Darwinism isn’t science. If I were a high school science teacher I would therefore have a dilemma. I wouldn’t want to teach Darwinism. I would be eager to teach the general facts of evolution. But the influence of Darwinism on young scientists would be something I would resist.
Given the current environment of science idiots and Darwinian worse than idiots I might well despair and advise students to study literature and the humanities. There are plenty of smart idiots who can handle the tech questions. The science brainwashing is an ugly personality trait, but as techno-morons we can live with it.
