They are not pushing common sense. They simply want obedience at any and all costs, even if you pay for it with your life. Common sense would say that, if you could be disfellowshipped for smoking on the grounds of defiling your body (which belongs to the beady-eyed monster thing, according to them), then what about doing something at least 20 times more defiling and getting those cancer shots? And the boosters every 6 months?
It is becoming obvious that the Filthful and Disgraceful Slavebugger wants people to suffer, to do more work while suffering, to trust in that beady-eyed monster thing to protect them and if necessary, to resurrect them, and get those torture shots. This is not about defiling your body (and neither is smoking), it is about obeying the Filthful and Disgraceful Slavebugger no matter what.
For the record, no I am not going to smoke because it wastes money and ruins your health. And, for the exact same reason, I am not getting those cancer shots--the Amazon "shot" is good enough.
