No, you're right. I wasn't aiming at a "be-all, end-all" post though... just highlighting some common ways people piggy-back their preferences on "UX". However, your suggestion is good and I added it to my (relatively short) list of articles-to-do. To be fair, a good UX conversation can take many forms depending on the project and context, but there are certainly key points to cover no matter what.
Thanks for stepping back in to clarify. I think what hurt this article the most was its emphasis on conflict over collaboration. How can people work around these habits of dressing up preferences? Telling them to 'call bullshit' is kind of empty, and it sounds like you've got experience that can inform those situations better.
