I would imagine it would probably be because if someone did something like this that was pro-trump, they would be crucified because the sentiment among the vocal group of people right now is very anti-trump or anti-trump's policies, and unfortunately we cannot have a good debate without one group demonizing another. I just don't see how encouraging someone to say a line in front of a camera is anymore brainwashing than encouraging people to spend $30 on a red trucker hat that says "Make America Great Again." People who support the message will look for an outlet to show said support. It doesn't mean they are brainwashed.
Well that was short lived, lol.
