I deeply relate to those "go witnessing on worldly holidays" horrors. It was almost as if the org was deliberately making us do things to humiliate ourselves and outrage the people in our neighborhoods. I also just quit doing it (even while still an elder and before any serious attempts to leave it all...). With me it was a common courtesy issue -- I always made it a point to be extraordinarily polite in the FS to make a good impression on the people.
I remember reading an article on Mormonism and their missionary boys in Time or Newsweek years ago that turned on some light about this. It said that it was well known to the Mormon hierarchy that probably only a hundredth of a percent of those missionary boys ever made a convert. They kept doing it as a reminder to the public of their righteousness and as an important "rite of passage" for the missionary boys themselves.
I now think the WT org is just as cynical - they love to put the R&F into untenable situations to mind condition them to obey unquestionably. Also they love to irritate outsiders and make themselves look as weird as possible. A little "persecution" always comes on true christians - even if they brought it on themselves. Weird is good. Shame and embarrasment for the R&F in door to door is good.
So, JW pubs - lets go hit em on Thanksgiving afternoon about 12:30 or so and tell them how the pilgrims were all demonized gluttons, then ask for some money for the mags.
SICK!!!!
