Donald J. Trump isn’t bashful about condemning groups or people with which he has issues.

*  Illegal immigrants? They’re “rapists, murderers, drug dealers. And there’s a few good ones, I’m sure,” he has said.

* Radical Islamic terrorists? He wants to ban all Muslims from entering the country just to be sure that none of those terrorists sneak in.

* “Politically correct” rhetoric? Why, he just cannot stand those who hide behind his version of “political correctness.”

What about racists? White supremacists?

When he was asked about statements from longtime Klansman David Duke that seemed to support the Republican candidate’s views, Trump said he “didn’t know” Duke; he said he didn’t know about white supremacists.

And then, just recently, when the crap hit the fan over an ad that featured a picture of Democratic candidate Hillary Rodham Clinton, a pile of $100 bills and a symbol that looked to many of us like a Star of David, Trump took the ad down. Critics jumped on the ad as an anti-Semitic statement. Then we learned that the ad first appeared on a white supremacist website.

Trump has yet to condemn Duke — other than to say he “condemns Duke.” And he has yet to issue anything resembling a declaration of condemnation of those groups.

Is the GOP nominee-to-be a flaming racist? I won’t say “yes.”

It is fair and reasonable, though, to wonder just why he doesn’t condemn those individuals and hate groups with the same zeal he condemns others.

Come on, man! I know you can do it.

If you want to.
