YABU. They state that 3/4 of people agree with breastfeeding in public, 1/4 of people disagree. I don't know whether this is an accurate number or not, but that's irrelevant. They are not saying "don't breastfeed" - they are just quoting a statistic and asking the viewer for their opinion (which if this thread is anything to go by, they've got).
BTW is it "actually illegal to tell a breastfeeding mother to 'put them away'"? Surely if a mother walking down the street said "put them away" to another woman, who happened to be breastfeeding, that can hardly be a criminal offence? Rude, wrong, but not criminal.
