Richard Dawkins is, arguably, the world's most famous atheist. He opposes religions of all stripes as "false," dangerous and anti-scientific. And while that stance has earned him the opprobrium -- and, presumably the prayers -- of many faithful people in many religious traditions, it's rarely gotten him bounced from a speaking engagement.

Until now.

Radio station KPFA in Berkeley, California, canceled an event featuring Dawkins -- in the video above, he uses the rather charming term "de-platformed" to describe it -- because the station didn't like the author's "assertions during his current book tour that Islam is the “most evil” of world religions, Twitter posts denigrating Muslim scholars as non-scholars and other tweets," as a statement from the radio station indicated.

This generated somemainstream media coverage, with The New York Times coming to the fore:

Henry Norr, a former KPFA board member, criticized Mr. Dawkins in a July 17 email to the station. “Yes, he’s a rationalist, an atheist and an advocate of the science of evolution -- great, so am I,” Mr. Norr wrote. “But he’s also an outspoken Islamophobe -- have you done your homework about that?”

Lara Kiswani, the executive director of the Arab Resource and Organizing Center, which is based in San Francisco, also emailed the station last week. She said Mr. Dawkins’s comments give legitimacy to extremist views.

“KPFA is a progressive institution in the Bay Area, and an institution that reflects social justice,” she said in a phone interview on Saturday. “It isn’t required to give such anti-Islam rhetoric a platform.”

Quincy McCoy, the station’s general manager, did not immediately respond to an email seeking comment. In a KPFA news broadcast on Friday, he said the station “emphatically supports free speech.”

Except, apparently, when that "free speech" offends followers of one of the three Abrahamic faiths.
