I am fully on-board with walkable cities, it's something I feel very strongly about. This link, however, is not to an article supporting the lofty claim of the title (currently "Lack of Walkability in the US is destroying mental health"), but rather to a shop where you can buy red Trump-style "Make America Walkable Again" hats.... for what end exactly? Not clear. The site is collecting donations, but they don't say what they plan to do with them. All of this smells very fishy. (As an aside, I'd guess the number of US residents who support walkable cities AND who are willing to wear a hat that is designed to be mistaken at first glance for one supporting the former president is very small.)
If you're interested in a more informative discussion of city design and its effect on lived experience, I recommend Not Just Bikes [1].
