Maher is obviously a very smart guy, and he has comedic timing and I do find him quite funny a lot of the time, but also has a bunch of effin' wacky quirks that makes him infuriating to watch sometimes, like his knee-jerk defense of Israel and anything it does, PETA, his constant hardon for anything "anti-PC", and (maybe he disavowed, I dunno), antivaxx nonsense.
Another of his dumb infuriating ideas is that fascists should be shown on TV to be exposed and shamed, somehow. 'Sunlight is the best disinfectant' or whatever he likes to claim repeatedly - NO! This doesn't work! It's been studied for chrissakes! Giving fascists and nazis airtime PROMOTES their cause! It lets them spread their poison further, more easily! Jesus effin' christ.
