“They are legally required to label these products “non-dairy”, because that is what they are.”
Sorry, but I straight up don’t believe this at all. I have plenty of parve things in my fridge that don’t say “non-dairy.”
“That also answers NC’s concerns about ethics.”
Even if such a legal requirement did for sure exist, that wouldn’t change my mind. I would just conclude that the law is unethical. US law isn’t Torah. Jews cannot treat it as non-dairy and vegans can’t eat it, so what is it accomplishing other than tricking people? If it were for allergies, it could say lactose-free.
