Dosent to me at all

They didnt even really counter your point, they gave another perspective to form a stronger argument of what your message was already saying

Parents should teach and guide their children moderation, especially for such common and addictive substances like sugar, especially when without moderation serious health and quality of life damages can apply

If a parents goal is to raise healthy humans with a high quality of life - they should be teaching and guiding children into moderation, not prohibition and the shame that goes with it, not hedonism and the shamelessness that goes with that

Its not that sugar is some fearful substance that should be prohobited outright, but its also not a substance without issue and should be moderated and controlled if modersation is not yet possible for such a still-developing human

There are many such substances that need this parental guidance, sugar is just the most obvious one to younh parents - a toddler probably/hopefully isnt hitting a 40 or a roach
