this means nothing

If you want to be taken seriously, provide data, proof, so that any outside observer can independently come to the same conclusion instead of taking your word for it. Asking people to trust you for [reasons?] and that you somehow for some reason are right and the other is wrong regardless of if they agree or not. This is the imposition of a viewpoint instead of winning your case, which is not a sensible point of view, and definitely not how you influence opinions.
