I agree that cutting ties with those who excuse abusive behavior is healthy because:
"The only thing necessary for the triumph of evil is for good men to do nothing." Edmund Burke
That sums up my dislike of those who persist in denial and attacking me for NOT being in denial.
I realize that most likely the denial isn't fully voluntary. There could very well be traumatic amnesia there, but that is not my problem nor should it be taken on by me as my problem.
As my C said, "I didn't cause it, I can't fix it, Not my problem."
