Instead should publicise the right teachings (very difficult to get it on the media) and do damage-control, i.e. when the MSM goes overboard saying "look at what Christians believe", a Christian says "I'm Christian and I think Camping is a conman"
I agree, basically, but I wouldn't say that Camping is a conman. I'd say he's deluded, severely mistaken and a false teacher who will not hear sound council, but I don't think Camping was saying what he was saying for profit though, at least not that I could see. Maybe I'm being too lenient on him, maybe not, I don't really know.
