Doctors bad-mouth cow's milk because a bunch of vegan pussies with their hippie propaganda have convinced a gullible bunch of half-a-fag pediatricians that dairy is THE EVIL. All it's going to get you is a bunch of lactose-intolerant pussy kids to match their pussy parents. And the sad thing is that they're not even going to have lunch money to buy their gay soy milk because my kid is going to be beating them up and taking it from them.
Actually, your argument may be valid for human consumption of bovine milk, but there are valid reasons for infants to avoid it. Cow milk has larger protein structures which are harder for human infants to digest than human milk. Cow milk has the wrong kind of fats for human infants. Not to mention that human infants need MORE fat than what cow milk provides. When infants are introduced to cow milk (about 12 months old), it should be whole milk. Children shouldn't drink 1% or skim milk until they are 2 years old.
As for soy milk, too much soy messes with male hormones.
