Everything trumpican gets through to them but nothing anti-trumpican does. So they only let in information that is conducive to continue to worship PIG because he has pre-programmed them to do so. Willing subjects, Easy peasy to convince. Once convinced they never ever stray or go away. Anything antitrumpican falls on deaf ears and is automatically labeled FAKE NEWS. Doesn't take genius to react to that level of "info". SIGH.
