Almost nobody had cable TV in the early 80's. I grew up during this period but believe what you want. Cable TV was barely off the ground. HBO, Showtime, Cinemax, but outside of that it was nothing. No reach.

Fast forward to the 90's when hate groups were allowed on the internet. No race riots, burning of cities. That only happened when things started getting banned. And the violence was not from the right. It was the left. They were the ones who looted and burned but again, believe what you want to believe. If you believe it then it happened. Right wingers burned and looted Walmarts..meh.
