I'm sympathetic to agile but it does have a quasi-religious feel to it. I've noticed that its proponents make claims about the right way to do things with an unwarranted level of certainty. When I ask "why" (politely) I seldom get a satisfactory answer and often they get offended by the very question.

All methodologies are created for people who do not understand "why", they are inherently religious. Otherwise why would you need a methodology if you do understand all the "why"s? You can just develop one much more suited for your people and your projects and fine tune it over time.
