If someone actually believes in and gives money to a televangelist, they are an even duller knife in the drawer of life. Dupes. Utterly willing ignorant dupes.
Although I have to admit, I used to be mesmerized by Dr. Gene Scott back in the 80s. He managed to brilliantly obfuscate the Scriptures using chalk and a blackboard and large words while repeatedly showing videos of his horse farm stocked with expensive Arabians. And the money kept pouring in from the willing dupes. Plus his second wife was hot.
It's a generally true statement that televangelists are hucksters selling the Gospel for a buck, or maybe a private jet - especially in places like TBN. But it's not universally true, and in any case that's no reason to attribute the sins of the father to the son.
You bring back memories by mentioning Gene Scott. My wife and I lived in California in the 80's. I remember him, and his show, and the saxophone. Don't think I ever listened to him speak. He was on Channel 56 with Wally George and the Japanese Samurai soap operas and the Racing Results from Santa Anita. I married horse woman, you see. Had to watch Trevor Denman.
