I want opinions!

Ok so I had someone tell me last night that how I want to feed my child is wrong.. Now when I have my baby I plan to (if my body allows) to breast feed. However I want to bottle feed my breast milk because that's what I prefer. I was told well you can't do that it's supposed to be bonding time.. Well what about women who feed there child formula?? You're saying they aren't bonding with there child?? Then I get well you can feed your child anywhere whenever you want... Ok or before I go out I pump to have supplies with me. What's the big deal? I was very aggravated and now my bf is trying to tell me I'm wrong even though before he didn't care. So I'm asking what's the fricken big deal as long as they are eating???!!!
