Actually I have some sympathy for them as performers, except in O’Reilly’s case. He seems pretty wrong there - blaming his unfamiliarity with some words on a teleprompter that sounds like it’s working just fine.
Performing is difficult, not screwing up can take a lot of effort, seemingly small things can disrupt that effort. I can understand it, as long as it doesn’t go beyond a hopefully occasional flare up of temper into abuse.
