If I am going to judge someone I will listen to them first. Generally I hate the idea of "judging someone", so I wouldn't even do that with regard to Bannon, or anyone else. But you need discernment as to whether or not to listen to a newscast. That is why I no longer listen to MSNBC, CNN, NY Times or many others that have knowingly lied to me with the intent to deceive. I can still quote them, just like you would call out a liar in a court of law. But my time is valuable and so I don't waste it on useless drivel. I skim through Bannon's show to see if there is anything I want to listen to but because politics is a big agenda for him, I haven't listened for a few months.
Other than the fact I will still listen to Bannon's news broadcast after finding cause to cross so many other channels off the list I don't know what your question is asking. It seems like a non sequitor. You judged Bannon and yet you didn't listen to him. To me that seriously harms your credibility to me and ironically raises Bannon's credibility a little bit because he has all the right enemies.
