I dont think there is a "best way".
I think all parents should think it through. What they decide is best for their kid is none of my business.
My intent here was not to say that I know what's best, I just wanted to elicit some thought on the subject.
Too often, I see a herd mentality on these matters, when there is usually a strong case to be made for another viewpoint.
I dont think parents protecting their children from bullies will always prevent therapy, or drug abuse later in life, although in some cases it may.
In some cases it will make things worse.
All of us have had to face down a bully or two in our lives, and the realization in that moment, that we can be strong, and defend ourselves, is something you can never give your child.
They need to find it on their own.
