In reading through the posts my initial reaction is Rumpole is looking at this from the perspective of a younger person, seemingly without children yet, who has somewhat recently come out of a very difficult life challenge which was governed in a particular way which worked very well for him. One of the realities, as I recall from so long ago, is that youth affords one the opportunity to have a point of view which doesn't always include the huge grey area of experience. And, it makes sense to me that because of his own experience, he advocates the way he found recovery. Without difficult child's to raise, without the suffering and angst that comes from that parenting path and the choices one faces that feels like it severs us from our own humanity, without age to offer perspective and with youth on his side, which can bring absolute certainty to issues without certainty...... and with promoting a path many on this board have looked at and bypassed which cost them their own sanity and health, I can see how this caused quite an uproar.
I can also see how Rumpole may be attempting to protect difficult child's he may see as being abandoned by us and perhaps that touches a part in us, a tiny part of our psyche, which feels as if we have, even though that is not the truth. The world can judge us and blame us for how our kids are and the choices we make about them, but in reality, at least in my opinion, no one judges us as harshly as we judge ourselves. Perhaps Rumpole brings that self judgement out. I believe we are all doing the best we can under extraordinarily challenging situations. In Rumpole's zeal and sense of rightness, he may utilize that point of view as an attorney to advocate for the difficult child's who will require that position. It may save a life someday.
I hope I do not offend anyone, this is simply my own point of view. There are a lot of different ways to find our way, and when it comes to our kids, we are all doing the best we can, all the time, I believe that with all my heart.
