Kind of a tradition thing for me and my siblings. If you grew up thinking it’s unedible then it becomes weird to eat.

For example most people from US would not eat cat meat even if they were given $10 to do it. No religious idea there it’s just “culturally unedible.”

This is different from octopus etc which are more so in “I didn’t know people ate it but I was never told it can’t be” or “neutral” territory.
