I'll have to agree with you. Bullies are not an monolithic organization with a single creed and method. And this changes a lot with age group as well. I suspect that most younger bullies are very much different from older bullies.

I don't want to repeat your post, but it really should all be repeated. You need to take away both their long term need to bully, as well as their immediate urge to bully. You can do so through a variety of methods. For example, that long term need to bully often (well, I think/hope it's often), just goes away as kids grow up. And that immediate urge to bully. Well, there's no deterrent quite like getting your ass handed to you by the guy who you just shoved.

And related to that, there are degrees of bullying. I dislike these school campaigns that stick all these different activities together as being equally wrong under the umbrella of bullying. I've seen material that tells children that all pushing/shoving and 'teasing' and being 'rude' is wrong and 'can be' bullying. I can't see this being effective in any way. All this can do is make kids think that adults and their rules are dumb. What do you mean I can't call Kevin, my best friend from before I can remember a fat dumby butt? What do you mean I can't shove him when I know he'll just shove back?

All that can do is make one subset of children dismissing the 'rules' and 'bullying' as a 'dumb adult' thing, and another subset (and I remember playing with this subset when I was knee high), that'll yell and scream abuse at anything 'against the rules'. Now granted, I was kinda in the 'these rules are dumb' group, so my view of things is a bit biased.
