Duncan, you are so eloquent, a magnificent author. You've completely persuaded me as to thinking this campaign is offensive. Your arguments are spotless.
But in all seriousness, you don't even begin to discuss WHY you think this is offensive. Maybe you could elaborate? Have you done some research that shows there IS a Hmong word for Hamburger? Have you done research that shows these people were forced to participate in this marketing campaign (I'm not calling it a study. It's a marketing campaign and nothing more).
Next time you want to share your opinion, please include your reasoning.
