What makes them think that being inactive in the field service or not watching or being at meetings means they are away from Jehovah?
Because JW's are an appearance based religion. It is not what you are, it is what you look like. You could be the worst pedophile, a drunk, addicted to illegal drugs, an embezzling thief, a liar, an adulterer, and as long as you made your required monthly quota of "field service" hours, gave regular contributions to the K.H., and match the grooming and dress that the governing body mandates, and if a male are appointed by the time you are 23 you can pretty well get away with anything.
