This could be cultural blindness, there's probably lots of places outside of your own culture that find eating insects the best thing ever. As hard as that may be for you to imagine, given your experience, which as it is linked to the culture/s you have lived in, is naturally limited.
Some examples that occur to me:
- Many Israelis may find eating pork disgusting
- Many North americans may find eating livestock intestines disgusting
- Many Anglo-saxons may find eating chicken feet disgusting
- Many non-Nordic folk may find eating putrid-smelling fermented fish (one is: Surströmming) disgusting
- Many non-South americans may find eating hamster meat disgusting
Yet for the people actually in those cultures they probably find it the best thing ever.
So I think it's mostly cultural (and temporal) blindness.
Here's some more ideas:
- "For Most People, Eating Bugs Is Only Natural" https://www.nationalgeographic.com/culture/article/eating-bu...
- "Eating insects has long made sense in Africa. The world must catch up" https://theconversation.com/eating-insects-has-long-made-sen...
I think cultural food preferences are probably strongly linked to food-source availability.
For anyone thinking I'm pushing some ideology, or food-preaching, cool your heels: I'm just stating some facts and making a point about cultural relativism.
When you use the world "normal" (especially for food), you probably speak with ignorance of other parts of the world.
