Working Moms vs SAHM, Breastfeeding vs Formula Feeding, Vaccine vs Anti-Vaccines. Do you think parents should stop bickering over this issue?

Agreed very much so, except for vaccination, unless you also keep your child at home and never let them out to interact with others. The others you have listed are all personal choice and circumstances; you have to do what's right for you, and it doesn't impact other people, so it should be nobody else's business to judge you. Not vaccinating your child helps spread diseases that will impact other children. It puts lives in danger.
