The nation is still reeling — more or less — from comedian Michelle Wolf’s performance at the White House Correspondents Dinner.

She belittled in a vulgar fashion the looks of the White House press secretary, using language I won’t use on this blog.

Wolf has gotten her share of criticism, which I believe is deserved.

There is another side to this matter. It involves the president of the United States, Donald J. Trump.

Wolf supporters say Trump is equally guilty of flinging insults, of denigrating people’s appearance or their physical disability. He uses highly intemperate language when he tweets statements at all hours of the day and night.

I’ll ask this of the president: Why don’t you, sir, start speaking with a lot more dignity and decorum when you criticize those who oppose you?

Trump gave Wolf ammunition she thought she could use against him when she took the podium the correspondents dinner. Just maybe the president could “disarm” his critics just a bit by adopting a more civilized — and, um, presidential — manner of speaking to the issues of the day.

OK. Having said that, I am acutely aware that none of this is likely to occur. Donald J. Trump is not wired to behave in a presidential manner.

I just had to put it on the record.
