Careful buddy, in my small brain, there's a WORLD of difference between a poofy-haired TV preacher tryin' to cajole you out of your dollar with promises of God's blessings; and a madman who wants you dead and your women raped!!! Worlds apart, thank you!
A person's belief in televangelism, TV wrestling, the lottery or Santa Claus doesn't hurt other people, so knock yourself out. The people who promote these things,while not guiltless, we'll let God take care of, if and when He chooses to. (Off topic, but those with biblical interest might look at context of 2 Peter 2:3 "...shall they with feigned words make merchandise of you:")
However, those that deceive people into harming others have passed from tolerated deception, to something that must be stopped by we the people.
There's the difference you rightly pointed out, not in the deception of people (the similarity I was alluding to), but in whether the deception causes people to harm others or not. One we can allow, the other we can't.
