Yes, it bothers me. I don't care one single bit what other adults eat or drink or smoke or inject, but I can get furious about what they feed their offspring. I grew up at a time and in a place where children were still considered property of their parents and there was no such thing as child abuse, except if you killed them. That has fortunately changed. But children depend on their parents for food and shelter. I know that most parents do their best and are mislead by big food and pharma, for themselves and their children. But I also think that any adult human being should have enough brain cells to at least for a split second think outside the box and follow instincts and decide that coke and fruit loops are as appropriate for children as vodka and cigarettes. I am also one who approves of government measures like in France to remove children from their homes if fed a vegan diet just like as if they were otherwise abused. I don't expect everyone to feed their children the absolute paleo approved super diet, there is a wide range, but many things that are given to kids nowadays as "food" remind me of decades ago when Nestle sent tons of baby formula to African mothers in a campaign that it was better and more nutritious than their breast milk, don't remember all the details but I do remember that Nestle was boycotted for years in Europe (where I lived). I should add that I don't have any children or grandchildren so it's easy for me to say, but I was a child once depending on my caregivers and remember it well.
I should also add that when I was growing up breakfast cereal was a bowl of organic oatmeal, meat was free range, eggs were as well and fresh daily, artificial ingredients were unheard of, fruit was local and eaten when in season, food in general was little processed and packaged, dairy was a big thing there and then, but raw and fresh daily picked up at the farm, and yogurt was home-made. That changed radically only a few years later but the cereal aisles in American grocery stores to this day seem very alien to me. And how someone can consider that food and not a drug. When I went paleo I only found back to my roots but without the oatmeal.
