You will find more details on the ignorance expressed in his piece by reading my response posted a few minutes ago.
I happen to have read the article on which the topic of white privilege was introduced into the academy, way back in 1990. There are FIFTY items in that list, culled out of more than 100 additional ones. It has its limits, but no white person with a brain who has read it would dismiss the concept as frivolously as "Skeptical."
Actually he should change his handle to "Not Skeptical Enough" of the claims arguing that white privilege doesn't exist. Including HIS OWN!
