Doogie (thinking Doogie Howser, remember that show) tee hee hee
Fading to some seems silly, juvenile, weak, fruitless, etc because leaving the jw's is such a personal issue. For some (perhaps you and I) it is as simple as saying "I am done, consequences be damned". We weigh the costs of saying so and find it a small price to pay.
For many others, family relationships, fear, guilt, shame, or being made an outcast are involved. I havent walked in those shoes myself. I am glad I didnt. My step family were the jws and I didnt give a damn if I ever saw or spoke to them again. But imagine if your son, daughter, parents, spouse was still a jw. Someone you care about and fear to lose.... Such a thing as saying " piss off" is not an option....You would use patience and fading as a ways to preserve what you love and want.
That is why some people need to just fly under the radar....they have their own price to pay for doing so. It is not like they dont want to say "take a flyin' leap"...but they suppress that anger and finality (and it would be final), for the sake of hope. That is very understandable to me.
I hope this helps..
