Do you consider a hamburger a sandwich?

[Strigon]

Merriam-Webster comes down as hamburgers being a sandwich, a sandwich being 2 or more slices or a split roll, and thus by extension hot dogs in buns are sandwiches. I find no fault in their logic.

Just because there's no fault in their logic doesn't mean we can go around saying it's right. They could define a sandwich to be any food with bread in it and it would hold up just as well to logic, but would be just as wrong.
