Terry made some great points about dillusions on another post. The problem with dillusions is they cause us to act in ways that aren't consistent with reality. When we act outside of what is reality, we can usually expect to get the well known "reality check". His analogy is that if you pretend a wall doesn't exist, eventually you are going to bloody your nose, bumping into that wall.
I think a wall that is easy to bump into is to demonize the JW. Believe me, I understand those who have become enraged by the mindless, runaway train that is the WT. The costs to me have been more than I ever thought I could bear, and they have literally taken from me the only thing that I ever hoped for.
But I think it is another thing altogether to take that anger, and what the WT is to me which is the greatest enemy I have ever faced, and apply that anger to each individual JW. They are not the WT. They are not even the JW. They are people who are "captives of a concept". They are dangerous. They are misguided. They are your enemy. But they are people. Just like us they have hopes and dreams. And when you reduce them to a one dimensional representation of all that is evil you are seperating yourself, to an extent, from reality. Additionally, when you have hatred as a motivation you actually end up becoming like what you despise. Eric Hoffer went into detail about how this phenomenon comes about in True Believer.
I guess it matters what your goals are. If your goals are to help your loved one to have the ability to have a different perspective, you are not served by giving in to hatred. It keeps you from behaving in a way that does not feed the persecution mentality your JW loved one. Additionally, validates their concept that people who aren't JW are so unbalanced.
In context of how you view other JW's, your hatred keeps you from reaping the benefits of the Godfather, "keep your friends close, keep your enemies closer". As an openly raving aggressor you are easily recognized and thwarted. As a cunning, hidden foe you are able to draw close to your enemy and "slit the throat" of his cult mind. You are able to observe and manipulate how your loved views those who influence him the most.
I guess it is a matter of whose needs you wish to serve. Your need for justice or your loved ones need for compassion and understanding. Just remember, nothing sticks it to the WT like a freed mind. Nothing supports their goals more then the hateful opposer who validates all the bonds of the JW mind.
