This is such an important point. After an event in Portland at which **THERE WERE NO CEMENT MILKSHAKES,** the entire right wing mediascape talked obsessively about cement milkshakes for days. In the minds of many conservatives, cement milkshakes were (and still are) real.
The New York Times even ran with the entirely bogus "cement milkshake" story.
The conservative blue checks were wall-to-wall with the cement milkshake story. Haven't checked, but I wonder how many have corrected the record. Also wonder how many have complained about the "Twitter mob" against the Covington kids.
Here's a good write-up (with receipts) of this "cement milkshake" myth that tons of conservative media outlets ran with, having not made any effort to independently confirm the story. mediamatters.org/laura-ingraham…
For example, concrete burns are pretty uncommon. Did any of these media entities with huge budgets contact the finite number of hospitals in Portland to ask if they'd seen a rash of concrete/cement-related injuries? I believe the answer to that is "no."
And we have a MAGA “concrete milkshake” sighting in reference to tomorrow’s pro-gun rally in Virginia!
