Do you remember the time he posted an advert for actors as being proof that the violence around the Unite the Right rally was probably started by agent provocateurs from the left/Antifa.
Then someone pointed out that the actors were needed in Charlotte, North Carolina rather than Charlottesville, Virginia where the rally was being held and a counter demonstrator run over and killed. He spent about four pages dissembling and deflecting rather than admit this obvious mistake.
It is obviously cringeworthy to witness but I am not sure about the embarrassment factor. If you have no self-awareness that these things are as plain to everybody else as the nose on your face then you can carry on as normal with your super-ego intact.
