Americans consider hamburgers to be a type of sandwich. It can be confusing to people from other countries who don't consider meat in a bun (as opposed to meat between slices of bread) to be a a sandwich.

Yeah. I'm from Sweden and when I think sandwich I think of this: http://i.imgur.com/hJwtQ7N.png

Sorry to keep doing this, but I would say a bun is bread, too: “A bun is a small, sometimes sweet, bread or bread roll,” quoth Wikipedia.

I guess likewise, because while bun is a type of bread, bread doesn't, again, necessarily have to be a bun.

Of course not. I’ve been saying for this whole conversation that it’s simply odd, when X is a subset of Y, to use language that implies that X and Y are disjoint sets.
