I'm not really advocating for anything other than pointing out that your argument is inconsistent. Is it about the sugar or not? If not then you've already accepted that there are different definitions and clearly juice is a different definition than a soft drink. Your arbitrarily deciding what's okay and not okay from what I can see of your argument. Adding healthy is even worse. That's an extremely subjective argument.
What about grapes? They're extremely high in sugar and relatively low in fiber. Is that okay? Do you see what I'm saying? There's no consistency to go on here.
