User stories are great, when they make sense and the people reading them and writing them agree on the methodology. Agile is fine for those who like the model but so is (trigger warning: anti patterns being complimented ahead) waterfall. I prefer Kanban but it works well for my team I'm ways agile doesn't. I like it so much, I talk about it. I also like user stories but for a different use case: SLOs. Surprise! I subscribe to the SLOs.
Any of the things I just said could be portrayed as one form of dogma or another. It's only a bad thing when people don't align. When people share or at least agree to a methodology, they're great.
What leads you to believe that just because you disagree with something then it's automatically a dogma and bad? If you're trying to debate the merits of an idea and you start your argument by dismissing and discrediting proponents, regardless of what they might say or how weak your points are, and to make matters worse you admit the proponents of said idea invariably win over your arguments, doesn't that suggest that there's some likelihood you're in the wrong?
If you read the rest of my post, you'll see that "questions as to the goodness of practices, or the lack thereof, are treated as personal attacks". There are other symptoms too, like questions being answered with non-answers.
Again, when someone claims that their way is the true way, and that everyone else _must_ follow the one true way, I believe that the burden of proof lies on them. Your opinions might vary!
