I don't think I am wholly alone in making many of my food (and perhaps some other) decisions on the name of the food alone, based on perceptions that often don't make sense. I know it's unreasonable, and I have been proven wrong sometimes, in that I have come to enjoy and appreciate foods whose names turned me off initially. Having not looked it up or yet paid much attention to anything written about it here, "kimchi" conjures images, in my mind, of rotting raw fish. Perhaps it's just because it sounds Japanese, and having actually tried sushi once, after being persuaded to overlook similar mental objections, I have come to view any food that sounds like it's probably Japanese negatively.
Plus, I ate (something other than sushi) at a Japanese restaurant in California once, and everyone had to sit at a large table with everyone else, whether they knew them or not, while some guy did parlor tricks with knives. I don't remember much about the food, but the experience was uncomfortable, so I am boycotting the whole country, at least as far as food goes.
Truthfully, kombucha and kimchi might be perfectly healthy and possibly edible foods or drinks, or whatever they are, but I'll probably never try them. As a nod to the kimchi lovers, I went most of my life refusing to try yogurt because the idea of eating squirming bacteria from a tub didn't sound like something that a civilized human being should be doing, but now I love yogurt. I suppose it helps that I know more about bacteria now than I used to, as I once pictured something like tiny little maggots.
