Yanbu, I don't think. Tbh I don't like it in children either.
But I'm not one of the "he won't starve" brigade either...some children really would. Phobias, allergies, texture issues...I get all those. My grandmother accused me of fussiness for turning down a sandwich. I have celiac disease ffs. 
However, my BIL, whom I will refer to as Twat for the purposes of anonymity, refuses to eat anything and is beyond rude about it. His wife, Doormat, has been bringing chicken fingers and yogurt tubes to family gatherings since her DC started on solids because she assumes they, like Twat, will not eat anything. Now, seven and five years on, of course they won't. (She also scooped them up and held them, trembling, whenever she saw a dog, assuming that like her they were terrified of them. :( Again, it's now true.)
But it could just be an attitude thing as others have said. Every family meal involves her begging the children to eat something. And every family meal involves comments about my DS in front of him and the other DC, and involving perfectly normal food.
"Is he really going to eat that pasta? It has olive oil in it." "Is he really going to eat brown bread?" "Does he really like pineapple?" Um...yes.
Twat has actually told my DS not to eat broccoli because "it's gross!" And at DS's birthday party I made sure to have hot dogs because I knew my niece and nephew would eat them. However, my nephew informed me "those are dirty." (They'd been grilled.) "We only eat the kind that you microwave."
However, I have a friend with a really fussy DD and she's extremely laid back about it. When they're out or at a family thing she has her DD look for something she'll eat and doesn't force anything else on her. If there's nothing, she says "oh well, you can have some toast later, you won't starve in an hour or so," and doesn't mention it again. Waaaay less irritating.
