A woman stood up to protest some comments from Donald J. Trump during a campaign rally for the Republican presidential candidate.

She was booed. Why? Was she being hateful? Did she try to shout down the candidate? Did she present a threat to anyone?

No. She was booed because was wearing a hijab, the traditional scarf that Muslim women wear to shield their hair in accordance with Islamic tenets.

The woman was escorted out of the rally. Kicked out. She left the venue to a chorus of catcalls.

It was a disgraceful display of intolerance.

What did the candidate do to tamp it down? Nothing.

Fellow GOP presidential candidate Gov. John Kasich of Ohio called the event “un-Republican.” Yes. It’s also un-Democratic and, I shall add, un-American.

Rose Hamid is a flight attendant who came to the rally to hear for herself some of the things she’d read about Trump, who launched into a tirade about Syrian refugees being terrorists.

Hamid said later that the characterization was improper and demonstrated the kind of intolerance and hatred we’ve been hearing toward people who practice the Islamic faith. It’s aimed at actual Muslims, not the perverted cultists who have twisted the religion into something unrecognizable to practicing Muslims . . . such as Rose Hamid.

Yet they are the individuals — the terrorists masquerading as Muslims — who draw the fire from political candidates, who use such rhetoric to inflame their supporters against others whose only transgression is to express their faith and to wear garments that give their religious identity away.

Kasich is right to condemn Trump, not just for allowing the ejection of the protestor, but for failing to calm down the haters scattered in his crowd of supporters.
