I found this article that seems to address the confusion between fear-based training techniques, which are identified as inhumane and dangerous, and overly permissive techniques that allow the dog to assume an inappropriate leadership role which is likewise ineffective and likely to cause problems:

Do not be fooled by the "dogwhisper" title, as this is not about CM. This is an article by a respected PHD with 45 years experience in canine psychology, and I think he would find merit in the techniques of both CM and Victoria Stilwell. But I think many staunch advocates and vehement antagonists of either often concentrate on minor differences and their own adopted dogma rather than recognizing the huge amount of common ground and good common sense embraced by both.
I don't know if that applies directly to this problem of SA. But the article does point out that a dog who does not respect his human, and either submits to him or her only out of fear, or has been allowed to control its environment without having clear limits set and consistently enforced, loses respect for humans in general, and may express aggression or destructive behavior when given the opportunity.
This is similar to the phenomenon that was pioneered by Dr Benjamin Spock
http://en.wikipedia.org/wiki/Benjamin_Spock and then taken to extremes of permissiveness which he never advocated. He urged mothers to rely on their instincts and treat their children as individuals, in a loving manner, but still given clear limits and appropriate discipline and leadership. These principles are also valid for dogs.
