This is what the argument is about on a deeper level. The proof that healthy eating is less expensive is undeniable. Because of this, they are doing what they always do when the truth conflicts with their ideology and they are shifting the goalposts. With this post, they are reframing the discussion away from the cost of food, because they will lose that argument, and onto the subjective, undefined, and ubiquitous white supremacy. You can't win with these people because they will always slip through your fingers like this when you corner them with logic.
