If it is the truth, spreading it will never be helping "the enemy".
Thinking the "best" of people sounds really nice, but it serves no one's best interests to stick our heads in the sand and pretend that people are good when they are not.
I already said I have no problem with a Christian owning a Bentley. Personally, I don't understand how that kind of excess squares with the calling of a Christian but I would never say that a person owning such is not a Christian. What I have a problem with is anyone, Christian or non, using fraudulent means to gain money. I don't know for sure if the Crouches are frauds. I have seen and heard them ask for money, though, and I've never once heard them, or heard of them, saying "We will use some of the money you send in to fund the movie that will help my daughter-in-law buy a quarter of a million dollar car."
The money came from somewhere and if it came out of a general fund raised by contributions to TBN it was given by people responding to the requests made on TBN. Probably TBN does not earmark money unless specifically asked to do so. It's probably not illegal. Just because it's legal, however, does not mean it is not a bit 'shady'. It just seems real fishy to me. Do you know the demographics of the people watching TBN? I think it's safe to say that the vast majority (99.99%) of the viewers are not wealthy and many are living on fixed incomes. Those people are giving faithfully to support the 'ministry' of TBN around the world. They give, they use public transportation or drive the same old Toyota they've had since 1982, and Matt Crouch drives a Porsche, paid for, ultimately, by the money sent in by little old ladies, struggling young families and middle-class blue-collar workers. If that doesn't smell fishy to you...
