There is also the problem that what you are putting on the screen is horsefeathers, though you might believe it is true.
One US Army helicopter pilot has a series of videos called 10-minute aerodynamics, and the diagrams he draws are so wrong it is laughable. But the wannabees lap it up and think it is the Trump Truth, and write adoring and idolising comments. How this guy got through army training thinking this way, is scary, his instructors must have taught him the same way.
