I agree with pp. What I hate about formula is the normalization of it. That it's completely accepted as NORMAL baby food. That so many people see absolutely nothing wrong with routinely feeding babies formula, as if it's what they are supposed to drink.
Do I think it's evil? No..my daughters were supplemented with formula most of the 5 months that I pumped for them, then had 100% formula from months 5-13. Did I EVER want them to have formula? NO. I absolutely agonized over the fact that it was necessary. I found it very difficult to even buy it. In the checkout line I felt like a fraud. Here I was a lactavist, someone who believes in and supports bf'ing 100%, buying cases of formula. I wanted a t-shirt that said "I wanted desperately to breastfeed!"
But are my daughters healthy? Probably..it appears so. I'll never know what difference having formula makes in their health. Do I believe that as a whole breastfed children are healthier? absolutely. I believe formula has a place, it's just not the FIRST place. It should be a last resort. And I think it should be avoided at all costs, it's not something to be used casually (like prescription medications) because it does have consequences, especially on the guts of very young babies.
My daughters had reflux that my son never had. They don't have any allergies thankfully, but I suppose that is yet to really be determined for all of them. I know they did not receive the same "feeding experience" that he has received, and I did not receive the experience feeding them that I wanted. My son has never and will never get formula, however not just because of the risks but because I knew I wanted to prove something to myself, that I could do it. That I could 100% breastfeed him. I needed to achieve that, given what feels like failure with my daughters.
I am pro-bfing, and to me that means supporting bf'ing moms in any way I can, which will in turn reduce formula use. I am for normalizing breastfeeding. Being anti-formula I think would be misdirected and not very effective.
