Thinking more clearly about "discrimination"

Here's a nice piece, called "Discrimination, or Intellectual-Lite?", at God, People, Place.  The author, Charlie Peacock, says (among other things):  

. . . I am committed to discriminate thinking, that is the intellectual ability to differentiate and separate – to tell the difference between one thing and another. What education I do have encouraged the promotion of discriminate thinking and the cultivation of the ability to evaluate, make comparisons, and categorize.

Yet, there is a disturbing trend among our American institutions of higher learning. In the interest of anti-discrimination, the keepers of our intellectual future have forgotten how to think discriminately – to tell the difference between one thing and another. . . .

For reasons I tried to set out here ("Confusion about Discrimination") and here ("Religious Freedom and the Antidiscrimination Norm"), I agree!
