If by "no one here speaks Tex/Mex except me" you are referring to forum members, I'm going to have to correct you on that claim, amigo.
I'm native Arizonan and except for 4 years of military, I have spent my life no further west than Mesa, AZ and no further east than El Paso, TX. And 2 1/2 of the 4 military years were in San Antonio, TX. Have had tamales, enchiladas, tacos, frijoles, and sopapillas for Thanksgiving dinner more frequently than turkey, ham, dressing, cranberries, etc.
But I just had a dental implant completed about an hour ago, so this year's Thanksgiving dinner will likely be an eggnog milkshake!
