At then end of the day we were all taught to rebuff difficult texts with a "this is what was really meant" argument. Sometimes the context and original language allows for more subtle or alternative interpretations but I long since gave up trying to twist others up in knots over texts from a book that is essentially a bunch of folklore.
Trying to convince a JW they are wrong based on texts like Phil 1 is an exercise in futility. The only time a JW starts to examine these details critically is when they are already receptive to re-examining far more fundamental teachings.
