Evolution is one of the three sacred foundations of political correctness, along with the notions that there can be no racial and sexual difference in mental capacities, and that religion is unprogressive and should be suppressed, Yet these are delicate things all three, and cannot well bear scrutiny. Thus the various determinists grimly avoid examination of their ideas.
Furthermore, The politically correct have a hard time reconciling evolution with the overwhelming feel-good glorification of the Blank Slate, proposed by Locke, which proposes the mind is conceived as a tabula rasa; it contains nothing at birth. Most PC's have to change hats between science class and social science class and claim the hat change never really took place
I had a wonderful opportunity I'll never forget to watch a liberal engage in "higher debate" one day on campus in some comm. theory course years ago and later expose his hypocrisy. In retropect it was probably more his indoctrination. In an open nuture vs. nature discussion, we were tossing around ideas leaving open the possibility of intelligence being hereditary, or even some of it; can we consider this new Bell Curve publication with the critical minds of university students? etc., suddenly this little pantywaist (never forget his name-Steffan,with the f's emphasized) had a complete meltdown and finally caused the class to screech to a halt with these high pitched screams of "Your point is moot! Your point is moot! It just is!
I saw Steffan in the library paking lot later that day, the veins having settled back in to his neck and his cognitive dissonace attack subsiding, getting in to his beat up Volvo with the Walking Darwin Fish sticker prominently displayed. I just shook my head when the irony finally struck me.
