I am a natural observer, I can say that you are absolutely correct. I am horrible at explaining though, so you're stuck with me only agreeing with you.
You as a person are taken into a "religion" on your own terms. You give your time to learn, to be aware, and to pass on any positive messages. WHen you see positive messages you pass them on in a non invasive way at first, and you progressively become more and more forceful with the way you deliver yourself.
As a mass religion, christianity has too much weight behind it, and modern methods of indocrination do not apply. You cannot compare Now with then, without assuming now is only now and not now and the future or now and the past, but only now. Scientology on the other hand is now, nobody knows what it was or will be, same as with pick up you can only assume, so some religions are VERY much like being in the pick up community. When you begin to put yourself in a place where you see yourself as superior to your peers around you, and you succeed in most parts you aren't sucked in to the madness, you actually succeed... e.g. tomkat.
P.S. The entire scientology religion started with hubbard, and dianetics. They use the BCE and AD to correlate to OUR 1950 AD so 1963, is actually 13 AD, kind of convenient to disengaging people from society. Dianetics was seen as mind manipulation back then, and scientology is actually recruiting, and "testing" a more mainstreamed method of gaining new members. They have series of tests for each level that you achieve, you pay to join the new level after you have been accepted, but you can't join if you pass the test. Its not as whackjobish as some people believe in the religion being entirely to sucker people in, its more complex... seduction communitys on the other hand do not go that deep.
