I can honestly say there are very few foods that I don't like. I'll try pretty much anything once, provided it's cooked well. Okra is on my don't-like list, but I'll even eat that if it's in a bowl of gumbo. And I'm not really big on brain dishes, either, though I've had them a few times. The thought of eating cooked brains doesn't disgust me, but the texture is kind of chalky and weird.
I am kind of in your camp. . . though, I have had some veal brains that were every so slightly tinny, but were like creamy scrambled eggs with a little crusty rim from the sear. I really, REALLY enjoyed them, to the point of feeling guilty. It was a dish that I knew was offal, it didn't try to hide it, but good lord it was amazingly good in a different kinda way I just can't put my finger on.
Okra, I like either fried, or just cooked enough to where it is "cooked", but not gummy/snotty/stringy. . .I have been to a few Ethiopian meals where okra is a standard filler, and it gets to the point where it's mucus like strings just take things over. . . screw that.
I have always made it a point to eat/try, because in life, with all the laws in place the regulate/prohibit things that could be everyday human experiences, FOOD is the ONE thing that is universal, it's needed, and the worst thing that can come from it(besides say a deadly allergic reaction) is you don't like it.
Food is something that is so varied, and differs regionally/culturally/religiously, but it is ONE thing in life that we can ALL enjoy/experience.
Could you imagine living to be a hundred years old, and on your final day, discovering a food that you REALLY enjoy, and have gone all that time without? Why NOT try different foods? What is the worst that can happen? We only live once, and food is an integral part of life, so why not make the most of it?
It's better to try it an not like it, than be a food wuss, and live off of hamburgers and chips your whole life.
