Dr. Ben Carson’s whole life has been very unusual, so perhaps we should not be surprised to see the latest twist — the media going ballistic over discrepancies in a few things he said.

Years ago, when I was writing some autobiographical sketches, I dug up old letters, to check out things I remembered — and was surprised more than once to discover that my memory was not always exactly the same as the way things had happened and were recorded at the time.

In the current flap over some things Dr. Carson said, the biggest discrepancy has been between the furor in the media and the irrelevance of his statements to any political issue.

For example, in a video someone dug up, Dr. Carson said to an audience that his “theory” about the Pyramids is that they were used as storage facilities. He was smiling as he said this, so it is not clear whether he was using this theory just to illustrate some point. But, in any case, he was not claiming this as a fact.

More important, the Pyramids are not an issue in today’s American political campaign, except as a “gotcha” gimmick.

Yet the media have paid far more attention to Ben Carson’s speculation about what the Pyramids were built for, thousands of years ago, than to outright lies Hillary Clinton told about tragic American deaths in Benghazi, within days after she knew the truth, as her own emails now reveal.

Another media tempest in a teapot has developed because of the mild-mannered Dr. Carson’s recollections about some childhood incidents in which he depicted himself as violent toward another child. Some people who knew the young Ben Carson have said such behavior would have been out of character for him. But has no one ever acted out of character, especially in childhood?

The media has not launched such attacks on President Barack Obama as they have on candidate Carson, even after Obama abandoned American commitments to provide defensive aid to countries in Eastern Europe and to directly promote the destruction of governments in Egypt and Libya that posed no threat to American interests — all the while undermining Israel’s ability to defend itself.

Meanwhile he cut back on our own military defense so drastically that even former secretaries of defense who had served during his administration have publicly criticized his policies.

But the media largely circled the wagons to protect Obama — and now to protect Secretary of State Clinton, who carried out the foreign policies that left America’s position in virtually all regions of the world worse than when the Obama administration took office.

It was much the same story on domestic issues. Obama’s outright lies, that people would be able to keep their own doctors and their own health insurance under ObamaCare, were far more consequential than Dr. Carson’s offhand speculation about the Pyramids.

Unfortunately, the moment Dr. Carson entered the political arena it became inevitable that the media would try to discredit him, since any prominent conservative black figure is a threat to the left’s vision and the Democrats’ voting base. The flimsy basis for the current attacks only demonstrates the media’s bias and desperation.
