HE IS COUNTING ON THAT! He wants you to be so disgusted with him that you stop listening stop caring stop talking stop thinking about ways to thwart him. He WANTS TO WEAR YOU DOWN to a nubbin so you withdraw and distance yourself and shrug it off and say WHATEVER!
He doesn't stop his evildoings. The only way to overcome him and win is to TALK ABOUT EVERY CORRUPT CRIMINAL. EVIL THING HE DOES AND SAYS EVERY SINGLE DAY! OUT HIM RIDICULE HIM CHASTIZE HIM ATTACK HIM. BUT FOR GOD's DON'T STOP CARING AND IGNORE HIM.
IF YOU DO HE WINS. EVER VIGILANT. DON'T GIVE UP AND GIVE IN AND ROLL OVER AND BECOME "ONE OF THEM".
Just a thought.
