Update: Correction in the comments. I was tempted to take this down but am keeping it up for my own admonishment.
There have been decades of complaints against people using the word literally when they clearly meant figuratively. Even CS Lewis was called to task for it in the 40's after a woman wrote in to correct him for making the mistake on a broadcast. He fully apologised, noting that she could not possibly upbraid him on this score more than he was upbraiding himself.
I believe things have gotten worse still. I saw this tweet today and realised I have seen usage like this before. I have recently railed against people using words like "unquestionably," or "undeniably," or "clearly" as bullying words, meant to intimidate others into silence by suggesting that they would be unable to mount enough defense to overcome what what the rest of the world considers "obvious." The reality is usually that the writer or speaker cannot come up with a logical defense of his own, and thus resorts to a shaming tactic. A successful refutation, once one takes a breath and considers it calmly, is often quite simple, though it usually would take some time, as much jungle would have to be removed.
"Literally," has now descended into that category. The statement he refers to is not only not literally true, it is not even figuratively true. It is untrue, but stated in bullying tone.
