I am not sure if I can dump dairy myself. But this article about how diary products are produced is interesting: “Got Soy Milk? New Investigation Underscores Reasons To Dump Dairy“. Now I understand why some people hate human beings more than animals.
I think even just for the sake of human beings, animal should not be mistreated. When animals are mistreated, what they produce is not good for human consumption. We may not die from it right away, but it may have adverse effects on our health.
