Is there good scientific evidence that rBGH is bad for you? I don't know a lot about this, but my first guess is that "naturalness" / "organicness" partisans are opposed to it for reasons related to the non-scientifically-supported ideas they have that are rooted in purity instincts.

In the US, on every carton of milk that advertises itself as being rBGH-free, there's a statement mandated by the FDA, who was apparently lobbied by the industrialized farms who thought such advertising unfair:

"The FDA has determined that no significant difference has been shown between milk derived from rBGH-supplemented and non-rBGH-supplemented cows"

Sure, but that could be true or false. Granted, in either scenario people who use rBGH are incentivized to want it to be true. I assume the fact that it's on cartons at all is a loss for the industrialized farms, though.
