"Horses are vegetarians."
Translation:Heste er vegetarer.
So "vegetar" also means "herbivore"? (Maybe it also works like this in English, my native language is Spanish and both words are clearly different: either you eat vegetables because your species has been biologically designed for that or you eat them because you have decided it.)
Well now, technically, herbivores not only have to eat plants to survive, but also choose to eat plants; so, they are vegetarians as well as being herbivores, but humans are not herbivores, even if they are vegetarians. Humans are still omnivores, even if they choose not to eat meat.
