I used to defend "Agile" against the "haters" in much the same way. As I gained more experience I began to see that most of what people claim is "Agile" is just prescribed processes trying to hitch themselves to the manifesto and the community it started. They have little bearing on what is or isn't agile though.

Scrum is scrum, if you like it fine, I don't. XP is XP, and so on. Each does in fact try to offer up a recipe for successful software projects. But there is no such thing as an "Agile" process. So, try to embody the principles and it may help you to be a better, smarter software developer, but even if you do it may be of little to help to cure a dysfunctional team or business.

Best of luck.
