I wouldn't throw in all the stuff about god, but I agree that it's unnatural for humans to drink the milk of another animal. Furthermore, if you decide to consume it, it should be in its raw state (where it's much easier to digest. You should get less mucus, fewer allergic reactions). Also, try to get your hand on goat or sheep milk. The milk from a goat is much more similar to human milk on a chemical level. Your body can tolerate it much better.
