SOHRAB AHMARI: Facebook’s lab-leak censors owe The Post, and America, an apology.

Is there something in the California water that makes Silicon Valley’s censorious dweebs so damned shameless?

On Wednesday, Facebook ­revised its policy of banning posts suggesting the coronavirus was man-made — because the COVID situation is, er, “evolving,” as a spokesman told Politico.

Gee, thanks. The flip-flop comes more than a year after the social-media giant banned a well-reasoned Post opinion column by China scholar Steven Mosher that speculated about a potential lab leak. Will our columnist receive an apology? Of course not. But it’s the American people who should be holding the Menlo Park ­tyrants to account.

Think about it: If you were Xi Jinping, and you wanted to deploy an information-control operation over the origins of COVID-19, you couldn’t have done better than to just let Facebook, working in conjunction with America’s bottom-feeding “fact-checking” industry, do its thing.

It’s almost like they’re working for the CCP.
