Facebook has done the absolutely correct thing by pulling down a Donald Trump re-election campaign ad that displays a symbol used by Nazis to designate political prisoners.

I cannot wait for the yammering, whining and whimpering to start now from the Trump team, complaining that Facebook is being “politically correct.”

The symbol is a red inverted triangle the Nazis would use to identify individuals bound for, um, death camps and other forms of political imprisonment. Indeed, it is reprehensible in the extreme for such symbols to show up anywhere these days, let alone coming from a campaign for a president of the United States seeking re-election.

As the Washington Post reported: A red inverted triangle was first used in the 1930s to identify Communists, and was applied as well to Social Democrats, liberals, Freemasons and other members of opposition parties. The badge forced on Jewish political prisoners, by contrast, featured a yellow triangle overlaid by a red triangle.

What in the name of common decency is the Trump team trying to convey?

They either are ignorant, arrogant or simply stupid.

Hey, I’ll go with all of the above.

Trump has decided to go after antifa, the loosely based collection of protesters often identified with far-left movements. Indeed, the word “antifa” is shorthand for “anti-fascist,” which is precisely the kind of movement that this modern-day group would oppose … and which was the focal point of Adolf Hitler’s rise to power in Germany.

Facebook acted correctly.

As for the ad it took down, well, it speaks volumes about Donald John Trump.
