The exact quote from the article is:
he expresses concern about how the ideas of the educated class have fallen from favor.
"The educated class believes in global warming, so public skepticism about global warming is on the rise. The educated class supports abortion rights, so public opinion is shifting against them. The educated class supports gun control, so opposition to gun control is mounting," he said.
If anything, I would take this as a suggestion, by Brooks, that the self-proclaimed "educated calss" needs to reconsider its position in society since it has become, seemingly, irrelevant.
