I just checked NMPF website and I checked the source code of that e-mail page and when you click the send button the e-mail goes to some IT at david.paolicelli@vivakos.com . Why they are not sending it directly to the commissioner? Are they filtering and censuring the e-mails? Is that even legal?
Besides, why their list has only “Milk”, “Yogurt”, “Sour Cream”, “Ice Cream”, and “Cheese” but doesn't include butter? Isn't butter dairy product? Of course they know that if they include butter then even the non-vegan people will start laughing at them (imagine you can't say peanut butter anymore). This way they are deciding which veggie source products can have dairy product names like butter, and which ones can not.
Last but not least is the etymology of the word. Just because in English the word milk comes from act of milking a mammal that doesn't mean that it's the same for all languages. For example, in Armenian, the word for milk is "gat" and that comes from "gatil" which is a drop of liquid. So in Armenian you can call a soy milk a milk but in English not. Does it make sense?

Well the dairy farmers are right here, it is not fair for them to use certain terminology if they are not licensed to produce those items!!
