Weinstein, who rose to national prominence when he opposed a 2017 event at Washington's Evergreen State College banning white people from campus for one day, said Thursday on Twitter that he had been "evicted" from Facebook. "No explanation, no appeal."

Weinstein's tweet included a screenshot of a Facebook notice indicating that his account hadn't followed "community standards" and therefore had been disabled. The notice said the decision had already been reviewed and wouldn't be reversed. 

"We are governed now in private, by entities that make their own rules and are answerable to no process," the professor and podcaster added. "Disaster is inevitable. We are living in it."

Weinstein is a full-fledged progressive, having supported self-described Democratic socialist Bernie Sanders for president. He also participated in the Occupy Wall Street protests in 2009. But he's also a classical liberal and participant in the so-called ‘Intellectual Dark Web’, where commentators speak out against cancel culture and defend free-speech rights.

The biologist appeared on the Joe Rogan Experience podcast in June, warning about the consequences of woke authoritarianism spreading from college campuses into the real world. As if that wasn't controversial enough, he spoke out against YouTube's demonetization of conservative commentator Steven Crowder in 2019.

Responding to Weinstein’s banishment from Facebook, Dave Rubin, another liberal who has faced backlash for his positions on free speech and libertarianism, said social-media censorship was inevitably going to spread from the political right to left. "They weren't going to stop with Alex Jones," Rubin tweeted.

Another Twitter commenter said, "We tried to warn liberals, when they tested this out on easy fringe targets like Milo (Yiannopoulos) or Alex Jones, that they were just the first but by no means the last. Can't say conservatives did not warn them."
