I think one reason why dogmatic advocating is so prevalent is that introduction of new processes and methodology to a team or organization requires considerable push. You have to overcome huge amounts of resistance from the people the changes concern, even if your role in the organization allows you to make the decisions.

If all developers would be "inquisitive, curious and pragmatic" you could probably rationalize the decisions and carry the necessary actions without evangelism. Unfortunately the world is sometimes awfully imperfect.
