Because science is complicated. It doesn't make for good sound-bites. It requires reasoning, which we all know is in short supply.
People want simple solutions, especially ones that vindicate their inborn prejudices. That doesn't change the fact of evolution.
That over-simplification doesn't take into account many things, such as the qualified men of letters who are not evolutionists. My son, for example is in the honors chemistry program with two Ph D's overseeing the track. Neither of the Ph D's are evolutionists.
People want simple solutions, especially ones that vindicate their inborn prejudices.
Careful.. If what you say is true, it is true of evolutionists even more.
That doesn't change the fact of evolution.
Now there we have a perfect example of compound problem involving the use of language and logic. Could it be an illustration of a simple solution vindicating an inborn prejudice?
