That would be the end of a lot of things. I would dump the LIE-ble officially, so I would no longer be bound to failing to follow it. The dress codes would be relaxed--and I would not want to see whole blocks of people with drab suits, starched white shirts with ties, and "sisters" with dresses of similar lengths. I would allow "sisters" to wear pants, even jeans, as they see fit (though cautioning them that sloppy dress such as pants halfway down are not only sloppy but could be unsafe). Jeans and regular shirts, so long as they are in decent condition (not unduly filthy), would be fine. That would eliminate dry cleaning bills. It would also eliminate sweat boxes when the temperature is around 35 C (or "sisters" wearing nylons when it is hot and muggy--I would recommend against it because they are uncomfortable). Shoes would need to be comfortable--not dress shoes, and no high heels that make walking difficult.
Next to go would be reporting field circus. What good is it to report field circus if half the reports are fake? And, what good does it do to go in field circus when no one is home? I have been in field circus all morning without finding anyone home, as often as not because of poor organization as bad luck in the territory. The "You are going to die if you don't join us now" would have to go--it was wrong since 1872, it is wrong now. Also, I would quit judging people for associating with disfellowshipped or disassociated relatives--being disfellowshipped would only mean you lost your membership, not totally ruining your life. And I would reinstate anyone, automatically, if their "sin" is found to be something that was written with a view of enslaving mankind.
That done, I would start teaching real spirituality. Do they know how to create real wealth? What would people think if suddenly this group came out of nowhere and got wealthy, without dishonesty, and started being an asset to mankind? I bet that would have more people joining than all the door to door work from 140 years ago. If people learn to use spirituality to heal properly, and to solve problems properly, I could probably get the numbers (the real numbers, not fake ones) past 7 million legitimately and go on to greater heights. And people would be less inclined to miss meetings if they learned how to do Jupiter squares, to use runes properly, and to genuinely meditate in an environment where they could be guided than if they have to refrain from doing anything that comes naturally.
Yes, that means Christmas. Though most people think it originated with Jesus, it was originally a pagan holiday. The washtowel had that right--and of course took the wrong stand. Yes, it is worship to the sun. And yes, it benefits mankind--as does the sun itself. Instead of ditching Christmas, I would teach people how to celebrate it properly. The period between December 23 (which is the actual day Satan views as His special day) and January 6 (the last day of Christmas) would be full of fun. You would be seeing the halls packed during that period, particularly on December 25 (more than for the REJECT Astaroth Party). That's when legitimate needs for new halls would start developing. And legitimate fun--in the form of celebrating something the witlesses have spent 87 years being afraid of.
Also, gone would be the "sins" involving fitting in with the world. I realize people need to salute the flag, even if they don't mean it, if they wish to fit in. Joining the military would no longer be a "sin". And neither would there be any questions about jury duty. What I would come down on is those hounders still insisting on enforcing the old "sins" designed to enslave humanity and imposing their consciences on the flock--it offends me more to see whole blocks of people in the same drab colors of suits and skirts the same height than even the sloppiest dress.
And, gone would be field circus as they know it. In phases, it would be trashed. People would realize that's the place to learn real spirituality, and that would be enough to get waiting lists to sign up. No more wasting time and gas pushing rags. No more braving bitter cold or extreme heat. No more having elderly people climbing mountains of stairs, sometimes in unsafe buildings. No more risking getting shot at, pepper sprayed, or having a dog sicced on you. No more going into a building where 20 people are smoking cancer sticks (when you are not even allowed to smoke). No more big dry cleaning bills. I don't think it would take long--within 3 months of using that organization to develop real spirituality and trashing the homophobic, sexist, racist, mankind-enslaving, hate-mongering LIE-ble, people would start wanting to see what really goes on. And, especially after the big Christmas party.
