I have not one single time invoked any kind of authority to make the points I'm making. It was only below, after you've (ironically) invoked the writer's credentials and insultingly proclaimed I never should be allowed to ever teach anything, that I let you know my qualifications.
20 lines of reasoning and one quote that I think conveys what I mean. I think if you can't honestly engage with that besides accusing me of "appeal to authority" there is nothing to be gained from continuing a discussion.
