I ask because I had this happen to me today and it really got to me. I had posted an article on a friend's Facebook page about child nutrition and a recent study linking giving junk food to toddlers to lower IQs at age 8. A friend of his responded saying that she gave her child junk food and she was fine and that bacon was really good for kids due to its choline content. I refuted with a journal article from a peer-reviewed journal that gave several healthier foods that provided choline in higher amounts than bacon. And, all of a sudden, she is telling me how someone who gave their child up for adoption has no business telling people how to raise their kids because I am obviously unfit to be a mother. She also said that I must be jealous of people with children and that was the reason for "judging" my friend. I have spent the last several hours trying not to be upset but I am. Have any of you experienced something similar and, if so, how did you handle it both directly (to the person saying the awful things) and indirectly (your feelings of self worth or lack thereof)?
