I read the link you sticked. I'm sorry you found a therapist like that. I have heard about the reticences and even the rejection from many therapists to treat people with borderline personalities. I guess these therapists projects their own issues and are unable to cope properly with these patients.

I'm sorry so much that you are having problems with your son.
I guess a good therapist could play a good role in this issue as well. I hope you soon find the treatment you deserve.
