Uh, this flips a hair trigger of mine. I don't know if there's an argumentum latinum pretensiosis for it.
"We do not interfere in the Christmas celebrations of others."
They are claiming a power or capacity or capability to do a thing about what people in the world are already doing, and have been doing, for centuries or decades, depending on the custom. This is consistent with their making themselves the center of the known universe and the center of time.
If a freshman science student were to test out this claim using metrics that quantify momentum transfer between the thermal exhalation of a JW at a door step with some panda cartoons on a beautiful snowy pre-Christmas winter day, and the motions of the householder as they wrap gifts, hang lights, etc, etc, that student would discover, separately and repeatably, in household after household, state after state, to at least the sixth sigma, that JWs do not possess, in the first place, the power or capacity or capability to "interfere in the Christmas celebrations of others", even if they were foaming at the mouth or slouching towards brains or titrating some mad test tubes to attempt to do so. Pretension to influence outside their cult. (Or, the mentally, emotionally, spiritually, psychically, ontologically, socio-economially infirm, which alas is a nontrivial %.)
