Sounds like you're not very open to diversity of thought. I've watched every liberal media bias shill - from Jon Stewart - whom is the least partisan of them all, to Bill Maher, to John Oliver, to Samantha Bee, to Seth Myers, to... insert anyone.
The more partisan one is... the less funny you are. Because instead of informative jokes - you're concerned with an overall agenda instead. It completely hinders and cripples you from instead being about information - and instead into a partisan agenda. You have a mission, and it isn't comedy.
Notice how Colbert went from hilarious shows to completely unfunny overnight.
Try to open your mind to diversity of thought.
