The speaker was appearing by Skype but that didn’t stop the protesters.

Protesters stop British nationalist speech at Columbia

Protesters opposing a speech by a controversial British nationalist at Columbia University Tuesday chanted “NYPD, KKK, how many kids have you killed today,” according to Facebook footage of the event.

The crowd had gathered to denounce and disrupt a Skype appearance by Tommy Robinson, a polarizing critic of Islam and immigration in Europe.

Students gathered inside Lerner Hall near the theater room that was slated to present Robinson’s talk.

Denouncing Robinson – who once did time for mortgage fraud – as a white supremacist and Islamophobe, many held signs equating his platform to “violence.”

A portion of the crowd broke into the anti-police chant while others declined to participate and kept silent, the video depicts.

Robinson’s appearance, organized by the Columbia College Republicans, was ticketed to accommodate 100 spectators.

He had barely begun speaking when roughly 30 student protesters who secured tickets entered the theater room and began jeering him into silence.

After several minutes of high volume chaos, Robinson’s address was aborted and he vanished from the screen.
