Everyone is very much aware that Oat Milk and Soy Milk and all the other non-dairy milks don’t have any cow juice in them
Just the name itself makes it clear.
It’s as equally stupid, in my opinion, as the argument that we shouldn’t call a vegetarian or vegan burger a “burger” because people might think it has meat when it doesn’t.
It’s all a play by the dairy and meat industries to make vegan alternatives sound unappetising, and it’s very transparent.
