I've never said that most epople shovel crap down thei children's necks! I just think the defensiveness cuts both ways, that's all.
As I keep saying, my threshold for what constitutes unacceptable "crap" is pretty high. My children don't live on organic radishes, FGS. I cited the Brain Licker as something I can't see the point of, ever, especially for a growing child. There are other things marketed at children which I think are just disgraceful poisonous crap and I wouldn't let my children have them, not even "in moderation".
With the reference to the "do you give a shit what other people's kids eat" which has got everyone (well, me and a few others) annoyed - I certainly wouldn't tut at people in supermarkets or pass comment on what other children had in their packed lunches or otherwise poke my nose into someone else's decisions at the individual level. But I still don't feel able to say "no, I don't give a shit what other children eat" - because at the social level, I do care, in that I think there should be stricter limits on what level of shite can be sold/advertised for children and how informed parents are about what is in their children's food (and their medicines!).
I don't go around curling my lip at other people's shopping baskets.
