I'm too young to remember anything from the time. I have many times heard people say "american schools classify ketchup as a vegetable" as if it actually was put into practice or true today, both in the states and while talking with people in europe. it's one of my earliest memories of realizing firsthand how "truth" is so easily manipulated.
I’ve never heard it put that way, more like “condiment as vegetable typifies republican thinking” as a shorthand for perceived attacks on national infrastructure.
