I guess I didn't explain clearly what I meant -- my fault.
Frequently I come across people who tell me, apologetically, that they can't eat cilantro at all "because it's genetic."
My point is that it's clear that many, many people with the same gene love the taste of cilantro. (I suspect I am one of them, since it tastes soapy to me.) It has more to do with your cultural cuisine (e.g. Portuguese), what you ate as a kid, or what you habituated yourself to later.
So you hate cilantro because you hate cilantro. Perhaps you hate tomatoes and parsley too, and pick them out of you food. That's fine. But don't pretend that it's any more meaningful because it's a genetic condition.
(And yes, in my head, if you pick all the tomatoes or parsley out of your food, I will think of you as a picky eater, though I won't make any mention of that to your face -- I personally feel that all pickiness, is a matter of habituation, and lack of developing "adult tastes" for food. Yup, it's a personal and highly judgmental opinion, I know.)
