It’s been semi-official for some time, but I feel the need to perhaps restate the obvious.

Donald John Trump Sr. views the world from a parallel universe.

He keeps yapping about seeking “unity.” The president keeps telling us he’ll serve all the people. He keeps making promises to bind the wounds that have divided us.

Then he pardons one of U.S. law enforcement’s most controversial, polarizing and divisive figures. Yep, that would be former “Sheriff Joe” Arpaio, the ex-sheriff of Maricopa County, Ariz.

Arpaio was convicted of a contempt of court charge. A federal judge ordered Arpaio to cease his roundup of illegal immigrants. The sheriff ignored the lawful order. Trump today issued the pardon while saluting Arpaio’s years as a lawman.

Arpaio’s conduct has been a graphic demonstration of racial profiling. He has sought out Latinos, arrested them and detained them simply because they look as though they’re here illegally.

The presidential pardon is just about as divisive a decision as the president could have made. He’s got his “base” of support on one side and the rest of us on the other. The “base” applauds the pardon; the rest of us are jeering it.

Unity, anyone?

Oh, and then he issued the formal order banning transgender troops from enlisting in — or serving in — the armed forces of this country. The men and women who call themselves “transgender” have served with honor, and some with distinction and heroism. To see the president order them tossed out is repugnant on its face.

How’s that for unity?

Donald Trump’s pledge to bring the nation together is now looking more like the empty gesture many of us have believed it was when first heard it in real time. He doesn’t understand how to do such a thing. Trump is not wired emotionally to carry out that serious promise.

His idiotic rant at that Phoenix rally earlier this week seemed to set the table nicely for what we are witnessing.

To think that he has done all this against the backdrop of what occurred two weekends ago in Charlottesville, Va. Go … figure.

Is any of that surprising in a man with zero public service experience — or interest — prior to his being elected to the nation’s highest office? It might be to some Americans. Not to me — or to millions of other Americans.
