I have a real life story about the indoctrination of those who watch only right wing shows, particularly FOX. About 12 years ago I met a married couple through, what else, youth soccer. Our daughters were on the same team for several years in a row so we spent a lot of time together. Both husband and wife were positive people who were fun to be around. About 4 years ago the husband developed a serious health condition that required him to quit his job and stay at home. I noticed a gradual change in him in that he seemed angry all the time, very unhappy. I figured it was due to his health but his wife confided in me that he was watching FOX news almost 24x7. He got so angry and bitter that he was impossible to be around, he became very isolated as well. This went on for almost 2 years until finally she gave him an ultimatum—turn off the TV or I’m done. He did and after just a few weeks she said it was night and day. He stopped being so negative and pissed off all the time. Stopped wanting to ONLY talk politics and instead tuned into his family again. He was visibly more relaxed and happier the next time I saw him.
I saw a documentary done by a daughter who experienced the same phenomenon with her dad. It’s real, I’ve seen it first hand.
