I'm not opposed, as protein seems to be a good target to prioritize, but claiming there's a war on protein just seems so out of touch to the point of absurdity. It's practically the only thing that people care about right now.
The few friends I've known were attempting ketogenic diets over the years kept focusing on the protein side when the actual diet is supposed to be dominated by fat. They've all experienced kidney problems of one sort or another, surprise surprise!
