''Those who are still in, yet know TTATT, are in a wonderful position though to sow seeds of rebellion within.''
Yes, they are in a wonderful postion to sow seeds of rebellion. But fading, by it's nature, means not sowing any seeds of rebellion.
And so it goes on.
Personally I don't think it makes much difference to other witneses whether another person 'fades' or just ups and leaves.
For me, my conscience and personal principles of honesty and integrity would no longer allow me to have anything to do with the religion once I finally realized what it really was.
For others I understand that fading is better for their individual circumstances.
