I wonder how many of us who have food dislikes grew up 'having' to clear our plates, and generally plates that we had no choice in accepting.
I have distinct memories of time after time sitting at the table for hours after everyone else left until I finished. I still don't eat meat, or coconut.
I was a tiny child, but I'm a little fat lady these days and I still struggle to throw food away. I have to persuade myself that I'm feeding the compost so it's not wasted.
Fish they gave up on after I threw up every single time. I don't think they really believed it until my Uncle told them to stop trying to feed me fish, that I was clearly allergic and they were potentially going to kill me...he was a doctor, so they actually listened to him. I think they thought I was being deliberately wilful. Everyone else in the family loved fish.
Years ago I met another person who couldn't eat it. His family are all NE fishermen, and he was due to have his own boat, etc., Instead the family sent him to do a butcher's apprenticeship and set him up in a shop. Folks thought it a great laugh
One of the reenactors couldn't touch fish either. Some numpty laid out a salmon on his plaid for a photo....did not go down well. Raised him up in wet itching weals across his legs. Meg scrabbled to find him anti-histamines in a hurry, and then flyted at the numpty who'd done the photo shots for being so damned thoughtless.
Mostly other folks seem to find other peoples food allergies, dislikes, etc., as a deliberate inconvenience and sometimes and affront to them.
