What would be " teachings of demons" as described at 1 Timothy 4:1, do you have an example of this?

Ever watch CBN? Those prosperity doctrine televangelists are the epitome of evil. I'm not a Christian and don't believe "demons" to exist, but those folks come so close I'm willing to say *if* I am wrong and they do exist, then people like Benny Hinn, Kenneth Copeland and Marilyn Hickey certainly are among that lot.
