How should parents and family members deal with false accusations?

Parents and family members out there are being bombarded with dishonest cult-like religious and special interest groups that relatives or sons/ daughters have joined. How have you handled false accusations? If these groups are so legitmate why do they need to brainwash people against family members to get their way?How should parents and family members deal with false accusations?
In the 70s and 80s, this issue was in the forefront of the news. It saddens me to hear that some families are still suffering because of this.





I hate to tell you this, but there is nothing you can do to erase the false images planted in your kid's mind. They are under the sway of a charismatic personality that is more powerful than any drug.





Back then, there were people who specialized in ';de-programming'; these kids. Parents had to resort to 'kidnapping' their your own child, isolating them, and intensive counseling during this isolation.





There was a book written by one of these deprogrammers, but I cannot remember his name or the title. Sorry. Also, one of the newsmagazines (no memory here either) tried to assist a family in retrieving their son. Finding him took about 2 years. He'd been with the cult for 20 or so years. It was filmed and did not have a happy ending. Wish I was able to give you some hope...How should parents and family members deal with false accusations?
I've been in a far worse situation than that. Still dealing with it. Let you know how it turns out.
