Teaching anything has to be done many times. Depending on the audience the degree of specificity that one goes into while teaching is variable. I personally read this as an attempt to teach and that teaching to be directed at newcomers to git. Nothing more. Anyone reading something like this as a newcomer is free to go on to become an expert and for their own opinions and practices. For an experienced practitioner to read a "Tutorial" and deem it dogmatic because it doesn't adhere to their specific and experienced approach ignores the fact that the practitioner has the benefit of significant experience that a new learner does not.
