I don't care. And just because someone gives nuggets and chips to a visiting child doesn't mean that's what their kids live on. They might simply give that as they know there is more chance of the child eating it.
And tbh if I went to someone's house with my ds and they were serving up plates of salad for dinner, I would think they were pretentious and that they were trying to prove the point that their kids eat better than mine. Because most children of my ds age would not tuck into a healthy plate of salad, but that doesn't mean they don't eat veg.
There can be middle ground IMO. Healthy diet with fruit/vegetables is essential, but even the chicken nugget and chips have their place.
