Like others have already stated... to each his own. Everyone is at a different place and each one of us would handle it differently.
However, that being said, I personally would not go this route. I would hope that 40 years from now, I will not have that much bitterness left. The WT$ has already sucked enough time, energy, and emotion out of me.
Those of us who were in for a long time or raised..err..brainwashed.... from birth realize that a reaction like that from an "apostate" only leaves the JW feeling righteously justified. And then they say to themselves..."That's why the society has such strong counsel to stay away from all "apostate" thinking" This behaviour likely reinforces the "apostate is a boogeyman, more to be feared than Satan himself" mentality that the WT$ likes to foster. At least that's how I know I would have felt about such an encounter 3 years ago. At that time, (when I was still a gung ho JW), an "apostate" would have fit that exact description: a middle-age raving lunatic who was borderline psychotic. Easily dismissed.
A sublte seed of doubt is likely to go further.
Just my 2 cents.
