Trump, with his endorsement of the fringe of Fox, as well as Breitbart, Druge, Infowars and worse and his denouncement of the rest of the Media has lent Presidential credibility of anti-Semitism and anti-Jewish conspiracy theories;
Far-right extremists are being told by the Q-Anon nutjobs that Trump is waging a secret war against the (((Deep State))) - and if you are the Pipe Bomber, you think he is wining and needs a bit of help, and if you are the Pittsburgh Shooter, you think he has lost and you need to execute the Final Solution yourself.
But both are part of a narrative Trump has help create and continues to popularize.
Well he is certainly not a populariser of reason and rationality.
