Seriously, you're going up against people who might actually have certifications and degrees related to diagnosing these problems. Your word is not law. Now, I sense a bit of a language barrier here, and I don't mean to make fun of you because of that, but honestly, I wonder if we're on the same page here. At any rate, you're still arrogantly saying your "advice" is correct, despite backing it up. I used to be exactly like you, proclaiming that my methods were law, and it got me nowhere. If you actually can take some criticism, and just know when to quit and start observing, perhaps you'll actually learn something, something you can be confident to offer, without having to fight people who actually know what they're talking about.
