I only drink diluted juice because it's what I was raised to drink. Pure juice, especially the grape variety, is far too sweet by itself.

Castigating someone for shilling for the sugar industry in the context of unsweetened fruit juice makes no sense. The guidelines you cite are obviously infants and toddlers. I suspect the poster above is thinking of more active older children. Accusing him/her of being a paid PR person is unjustified and unnecessary.

Do a search - the poster frequently recommends adding refined sugar to the diet; and responds to requests for cites with abuse. In this thread they've called citing your claims as "a game for retards".

The poster holds a view which is so weird it may as well be shilling. (And I say this as someone who has said that Lustig advocates go too far).

I stand corrected :-/

It is for these reasons we should ban breast feeding. Human breast milk has a sugar content higher than ice cream! It is obviously unsafe for babies to be exposed to so much sugar.

Breast-fed infants don't typically have exposed teeth subject to tooth decay, do they?

Sure they do. Not when they are first born, but later on. Source: Father of four kids who were still nursing when they had teeth.

On the other hand, it's not really a problem if a kid's milk teeth go bad. They quickly get replaced.
