"...it is usually Mexicans who run the mobile taco vans..."
How do you know what specific nationality a Latino taco van driver might be? Do you stop to ask, or is this just another of your racist assumptions? Perhaps every Latin person is automatically "mexican" to you?
You do realize that most of Latin America is not Mexico, don't you?
The taco van driver in my neighborhood is a white boy named Larry. Maybe I should ask him about pigs in a blanket? Being a white boy, I am sure he would know all about them. Or maybe I should ask him about toast, or bagels, or whatever the hell else white people like to eat these days.
You know, I don't think you should be allowed to use the name "taco" in your name until you become a little more racially sensitive to brown people.
Viva La Raza!

It's been a long time. Long time.
