For all the noise over the wave of post-election hate crimes supposedly committed by Donald Trump supporters, it turns out the real epidemic is one of . . . blatant hoaxes.

An African-American church was torched last month in Greenville, Miss., with “Vote Trump” spray-painted on the walls. The initial New York Times account had stressed the Trump angle, though Mississippi officials cast doubt on any “political” motive from the start.

Now police have made an arrest — of an African-American parishioner of the church.

Other well-publicized fabrications:

A Muslim student at the University of Louisiana-Lafayette admitted making up the tale of two men, one in a “Trump hat,” assaulting her and tearing off her hijab.

Also owning up to a hoax was the guy who claimed he was assaulted in Malden, Mass., by two men chanting “Trump country.”

White men allegedly accosted a University of Minnesota student, yelling at her to “go back to Asia.” Now police say they couldn’t verify the incident — and she responded by deleting her Facebook account.

A Bowling Green U. student claimed men in Trump shirts threw rocks at her. But cellphone records show she wasn’t where she’d claimed during the incident — and on Facebook she said Trump backers should “all get AIDS.” She’s charged with obstruction.

Here in New York, of course, Yasmin Seweid was charged for falsely claiming she’d been beaten by men chanting, “Trump.”

In each case, the media accepted the initial story hook, line and sinker — and stressed the Trump angle.

Even without the Trump connection, the Times and other outlets ate up YouTuber Adam Saleh’s tale of being kicked off a flight just for speaking Arabic to his mom — which now stands exposed as yet another fake.

Which brings us to the larger point: A week or two back, the Times and its ilk were all over the threat of “fake news,” which supposdely enabled Trump’s election.

Funny how as the “fake news” furor fades, the false stories confirm liberal bias.
