I think it’s because we humans like to lazily simplify things, and so we just dump objects into a category they don’t really belong to just because it’s convenient. Well, if you didn’t, I’d still call it a strawberry anyway. Same thing goes for tomatoes and potatoes. And oysters. In fact, I’d stick with the old names even if you were to change everything just for your sake. Might as well call the whole thing off eh?
