We are the only species on the planet that regularly drinks the milk from another species. That can't be good.

We are also the only species cares if poop is on our food...while I don't disagree with paleo diets, I always hear this argument for don't drink milk and I think it sucks.

I agree that is a terrible argument. We are the only species that does a lot of things; some of those are good and some are bad.

Another counter to that argument is that the ability to digest lactose must be beneficial in the evolutionary sense given how rapidly and widely the gene has spread.

And for the biology nerds, here's an interesting article discussing how lactose tolerance is perhaps the first trait in which scientists have been able to document convergent evolution in humans at the genetic level. Apparently the mutation arose independently in Africa and Northern Europe.
