"talks about things that he hasn’t actually experienced in a way that strongly implies that he has""In plain English: he lies."
The media seem strangely reluctant to use that simple, blunt word. When Trump repeated Blatant Lie #4,677 the other day, we were treated to a variety of phrases such as "He falsely stated", "Counterfactual statement", "Not supported by the evidence", "Claimed incorrectly", "Misleading statement" and other euphemistic waffle. Looking at other known liars, no reputable media that I'm aware of simply said "Foreign Secretary Johnson lied that {enter BS here}" or "David Davis told another outright lie today ...". Pretty much no one wrote in the last year, "President Trump lied when he said {...}".
And it's not just a problem of simply getting things right, there is more importantly the question of managing the epidemic of lying. It appears that an infection formerly confined to newly evolved social media websites, around 2000 jumped the species barrier and began to rampage through the human population. One high profile victim was British PM Tony Blair, previously a somewhat honorable man, who began to lie serially (possibly after contact with one Smirking Chimp, who was infecting Washington DC with equally deceitful fellow sufferers such as Cheney, Rumsfeld, Rove and others).
It seems that right-wing extremists, racists, bigots, religous nutjobs etc are predisposed for infection, since they have only tangential acquaintance with truth anyway. In this case the disease acts as a symbiote, helping to compensate for lack of evidence by providing comforting fabrications instead.
Arguably, the pathogen now having found high-profile hosts such as Donald J Trump, various British and East European politicians, and latterly even Elon Musk, it is attaining its pandemic stage and risks overwhelming the human race's immune systems such as science and education (and decency, common sense and integrity).
We can start by calling a liar a liar, but it may not be enough.
