I was raised by people who believed in personal responsibility. This means accountability. Though my parents were fundamentalist, I found ways to see TV. I was obsessed with it specifically because TV was forbidden. Television is a series of morality tales.
Roots made an impact on me. My parents were incredibly odd. They wanted me to see Roots. They went to Goodwill to buy a small, black & white TV to watch it on. I saw it when I was six when it came out in 1977. I guess you can write down six as the formative age for a child to see a mini-series.
They got rid of the TV. Bought it again to see Masada. Donated to Salvation Army. Bought a cheap one you have to turn the channel with a pliers. Watched Ben-Hur and Shogun. Then it’s gone. You get the picture. At any rate, I would blame Hollywood as much as anything…oh, I got to watch Little House on the Prairie and Star Trek. Those are very moralistic.
