Heh, I remember back when I was first an undergrad in Manchester, one of the independent student mags regularly took inside-front-cover ads from the Scientologists.

The small print "printed and published by" bit at the bottom of the contents on page three always had a "we recommend you ignore the ad to the left, they're paying us and we need the money"...

That said, more potential-Scientologists will be influenced by an argument based on the relative prices of placebos than by a "none of them are necessary" argument, and those already of no faith may be deterred by drawing a comparison with other religions.

I think I agree with this, while I'll not be sucked in at all, I'm not the target, it's those "looking for meaning" etc that they're going for. I haven't seen any of the actual stuff they're putting about, just online stuff that gets linked to. Ah well.
