John Oliver is a self righteous dick. Plain and simple. As are Colbert and Kimmel. That damned "Daily Show" pretty much wrecked comedy for a generation with all those "let's make up fake stories about people and then tell jokes that make them even more fake while we smirk at the camera and all our courtesans laugh" fools.
Corden and Fallon tried to stay neutral but New York and LA leftists will not have it. They were made to tack left HARD or give up their careers. They toed the line.
Leftism is why we can't have nice things.
