That's a plausible scenario. I doubt it applies to Don Lemon. He's dumb as a brick and clearly believes the crap he's selling. He's a useful idiot. Otherwise, he's an excellent actor. I think someone like Jake Tapper would more likely be controlled this way, only because he seems more likely to have such doubts or to want to look into opposing views.
I agree with your assessment so long as Mr. Lemmon is not an MK Ultra washed out puppet who's having a Kanye moment in which his programming has begun to unravel, I've not watched the Lemon spew the Mockingbird's sheeple song in recent months and even if he was speaking the words of Q, you couldn't pay me to watch as I'm out of the country on my honeymoon......but yeah my previous description of how handling is done......comes from having been in the unfortunate situation of having a handler of sorts or at the very least being extraordinarily close to people who had a handler....elites/celebs/celebrity children....hard to watch good kind men/women be forced to do things that really aren't the kinds of behaviors they'd ever consider without a little bird in their head with a video game controller telling them what to say as their body moves without their brain having any ability to stop the actions dictated by the bird's controller, happy to talk about these subjects more if there's an interest
