All of these different foods are a cultural thing. It truly depends on where you grew up, and how your parents were about having you try new foods! I grew up trying and tasting all different kinds of game meats (Dad was a hunter and fisherman).
To this day I do and will try just about anything, except for our rodents, (Eww, racoon, possom, badger, not even gonna try it)
About the only things I hate are brussel sprouts and chocolate pudding. Tried those, would rather have another veggie, thank you. If that is all you have, well, I will happily pass the dish. I would MUCH rather have pickled cabbage with flaming red hot peppers and octopus in it!
I love watching those shows on the travel channel where they go all over the world and try the different cuisines. I have been lucky enough to have travelled the Orient as well as across North America (we eat some pretty rough stuff, too) I am looking forward to going to Puerto Rico this summer, and will NOT be eating at McDonald's.
