All silliness aside, I'm in complete agreement with the statement that "nothing good will ever come from killing a grizzly bear". That's not to say that some bears won't be killed for sound reason (man-eater, over habituation with humans), but, it ain't good.
I'm a big fan of the great bear. If, in this modern world, there is such a thing as an personal animal totem, as some native Americans believed, then the bear is mine. I've read just about everything I can get my hand on about ursus horribilus - Doug Peacock's work is particularly good. The problem with the bear and with humans is that they are too similar in some ways - they are both remarkable omnivores, long-lived, territorial, remarkably adaptable to habitat, intelligent, and individually unique - which is to say, like humans, they have individual quirks because they are learned animals. This is part of the reason that native American communities often referred to the bear in human terms, as a relative, or the sentinent spirit of a deceased human.
Most animal babies spend very little time with their parents - perhaps a season for birds, many mammals, even less for reptiles, fish, amphibians, insects, etc. Social animals, with a group/herd/pride hierarchy, spend longer, but often reach adulthood within that structure within a year or two, and don't receive much individual parenting for even that long. Grizzly bear cubs spend over two years with their mother, being nurtured, and being taught.
While all animals rely upon genetic programming to function, there aren't too many - mostly long-lived mammals with social structures - that seem to rely heavily upon learning and thinking and adapting as they grow. Bears aren't as social as lions, elephants, orcas, wolves and humans, but they do learn from momma, and they do seem to think and adapt. As I said, I'm a big fan.
