I see that the conversation has shifted from it's original premise (I think the already-mentioned ad-hominem and package-deal fallacies cover it anyway) to the premise of religion as a scam business that doesn't produce anything.
I don't really see the point in vilifying people who sell a product as ephemeral as an idea or a 'way of life' as an argument against religion when there are certainly people involved with atheist philosophy and miscellaneous secular 'ways of life' with the same modus operandi. As long as people have ideas they wish to promote... and as long as other people are willing to pay them any mind at all... they'll find a way to profit financially from it.
I mean, you can call Dennett, Dawkins, and Harris "real scientists" but what tangible scientific advancements have they honestly made? I can't think of any electronic or biochem technology they've contributed towards producing. No new machines, no new vaccines, nothing of THAT sort. It seems to me that all they've done is sell their ideas. For example, the only contribution of the much-praised Richard Dawkins I've ever encountered in day-to-day life is the treat of seeing the word "meme" brought-up every time someone wishes to reference a stupid internet fad or phrase. I admit it's an interesting way to repackage and sell gene theory as applying to general information transfer but it's not like I've ever heard it used in conversation (on OR off the computer) to reference anything OTHER THAN a goofy quote that had made its way into cyberspace. So yeah, he invented a new term (...well, borrowed from old terms) and brought it into the modern lexicon. It's not really that impressive when you think about it, especially when you think about which people tend to use it most frequently.
Then there's people who sell 'ways of life' that avoid religious overtones and stay within secular territory. Tony Robbins, 'Dr.' Phil McGraw, and other "self-help gurus" have made ridiculous fortunes by telling people how they can "live better lives", coming out with all sorts of books and personal well-being products in order to sell their programs. In terms of 'vetting your product', what else is there for things like that other than "if it worked for me/her/him, it can work for you too!!!" ? What about all the different workout gadgets and videos being marketed these days? You don't need them at all in order to be fit and healthy (and the people who promote them were almost certainly fit and healthy BEFORE the product came along)... but is it then fair to immediately presume that they wouldn't help you even if you actually DID use them?
...
So, are ALL THESE THINGS "scams"? Is it wrong to profit from an idea if people come to you en-masse to learn about it? Is it immediately an underhanded and shady venture if your business doesn't produce something of tangible worth (other than books and audio tapes) and only alters the way people think and feel about themselves?
What about 'ways of life'? If your product is the idea of some manner of living, and the people who buy into it see either detrimental or neutral results instead of beneficial results, is that immediate cause to blame the product itself, or doesn't it matter how the people actually put the product to use? If you buy a DVD of workout exercises but you never actually get up off your butt and follow them (or you only perform them at incredibly infrequent intervals) is it really the DVD's fault that you're still fat?
Anybody get what I'm saying here?
