Simple. If the people in a position of power aren't being nice and don't want to have to change and know this deep within the depths of their very souls...they will kill the man not only in the worst way imaginable but also attempt to disgrace and demean him in the eyes of the people in order that his words may die with him. Even if there deep down, they know their plan won't succeed. At least, it will fail in ways that they would most like it to succeed and succeed in the least important details. And dare you ask what government would execute Mister Rogers or Captain Kangaroo? Haven't there been governments to execute their ideals already?
