I went with AAAB for the poll as it seems fairest, but reading your explanation changes the situation a bit. Outside of situations where affording and obtaining food are major issues, no one should have to persist in eating foods they dislike as though it's an issue of morals.

I am a little biased in that I'm a very picky eater who had allowances made for her as a child. It's possibly meant I have limits on my tastes as an adult that persistence in childhood might have done away with, but it would have been hard to do otherwise with me. I refused food when there was no alternative and gagged on food I disliked - my parents were reasonable where I wasn't. Or where my tastebuds weren't; I'm almost definitely finicky because of supertasting, and it's annoying to feel a need to scold myself for a quirk in genetics because of maxims like "eat everything that's put before you" and "clean your plate".
