Psychological conditioning made for viewers to ridicule opposing ideologies/people with logical fallacies without ever engaging on substance.
If you have ever tried to argue with a liberal, you’ll notice that 90% of them will attempt to ridicule and then try to disengage without ever having a discussion.
Most television is outright psychological conditioning. Society is a reflection of the mass work done upon it. Thank John Stewart and Colbert for spawning todays modern leftist. All hate, little substance.
