Please you guys who have children lost to the cult, NEVER give up, it is a cumulative thing with everybody who leaves, each piece of information, or reasoning, or pure love, that comes from outside of the cult, adds to the conviction that grows in the heart of such ones that something is very wrong within.
I shed tears for you all, I know the pain I would feel constantly if I was alienated in any way from my sons, and the fault is not yours! That makes it harder to bear.
But please, keep on showing your love for them, telling them of your love for them, love conquers all.
