I'm genuinely curious about the idea that "everyone says that formula is best"? Where are you hearing that? I have done a lot of work with breast milk advocacy. I have never heard anyone advocate formula as a superior product to breast milk. I think some people think that the "breast is best" message has gone to far, but even those people don't think formula is superior.
Part of the feeling that there is a "dangerous growing divide" is when we start to dehumanize the other side - the people who vaccinate hate breastfeeding and only feed their kids bacon from pigs raised in terrible conditions while allowing them to place first-person shooter games starting at age 2.
