YOU’RE GONNA NEED A MUCH BIGGER BLOG: Let’s Talk About Left-Wing Quackery.

Right-wing bubbles are a reality, yes, but let’s also take a hard look at the seldom-discussed left-wing echo chambers, where outright lies and fabricated narratives similarly grow and metastasize into larger, more dangerous “truths.”

For all the talk about the right-wing information ecosystem, there’s remarkably little daylight between the communities that inspired the 2016 Comet Ping Pong incident and the communities that encourage lethal resistance to the “trans genocide.” The chief distinction is that left-wing crankery is often justified and defended by the mainstream institutions that are supposed to serve as a sanity check on such things — institutions that would swiftly condemn similar nonsense if it came from the right.

But if you believe the one is dangerous, consistency requires you hold the same for the other.

Let’s speak honestly, then, about the dangers of partisan insularity, starting first with those communities where it became widely accepted as a “fact” that former Alaska Gov. Sarah Palin inspired the 2011 Tucson, Ariz., mass shooting, in which a mentally disturbed man killed six people and wounded 13 others, including then-Rep. Gabby Giffords (D-Ariz.).

There is no truth to this claim. There never was. It’s mostly an invention of former New York Times columnist Paul Krugman’s award-winning brain.

Yet this myth became so normalized within certain ideological circles that the Times casually repeated it in a 2017 editorial. Palin sued the paper for defamation. She lost — it is nearly impossible for a public figure to win such a case in the U.S. — but what the Times published was still clearly false.

Scratch a normie Democrat or radical left-winger, and you’ll likely find a collection of “facts” that are actually urban legends, outright lies, carefully crafted agitprop, or some weird combination of all three.

Read the whole thing.

Incidentally, Krugman doesn’t actually believe what he wrote about Palin back then. Otherwise he would never had said recently: Krugman Tells Businesses to Cut Ties with Trump or ‘You’ll Hang.’
