You are a rider of limited experience who has never ridden any dressage test -- western or classical -- at any show, recognized or schooling. Nothing wrong with that. And there's nothing wrong with asking questions, either. The problem comes when you get answers from people with more experience and knowledge than you have. And you don't like what you hear.
You need to stop reading about dressage and start doing it. Or at least listen with an open mind to people who have. You don't have to agree with every one of them. But you'll learn faster if you stop arguing about things you really don't know much about. There's no shame in being a novice. But being ignorant and stubborn just makes an annoying gadfly.
