It’s another symptom of alienation. People try to reclaim agency by acting out against what seems to fall out of control of industry and media. America is an urban, developed society so things like raw milk and meat only diets seem both authentic and transgressive. There is a certain level of glamour to these things because they are out of sight for most almost all their life, even if they buy their raw milk in a carton and their meat prepackaged in a grocery store.
It’s impressive how much French are able to get away with in terms of chauvinism, jingoism, imperialism and neo-colonialism not to mention implicit or explicit racism. They managed to craft, I believe by design, an image that appeals across a broad political spectrum by sustaining the view that France is a prestigious and romantic country that ironically is amplified and projected even further by Anglosphere and has purchase even in many leftist circles who idealize France and French.
