The relational modeling of TV is to deride others and criticize and put down loved ones. All this is done for the sake of humor. And it works. It is humorous. No wonder these same kinds of critical put-downs show up at home, in schools and at church.
TV is a bad model for interpersonal relationships.
It makes it easier for me to use put-down humor. I ought to just unplug it, I suppose. TV promotes the sin of materialism. TV engenders coveting, materialism and idolatry finding joy in things. TV is a social evil.
