I guess what ever country you live in food from that region seems normal but if your from another may seem abnormal. Generally a diversified diet is better than a narrowed one with limited nutrients. Too much of something’s can cause problems too like colon cancers usually white flour or white rice in different areas of digestive tract. Japan kills all those friendly dolphins. It’s what they’re indoctrinated to.
I don’t know if Americans would eat Roos on a regular basis other than to try it, possibly see them as victims especially women. Koalas too. They may see things like that or grubs as survival food. They were raised in a controlled environment some of which was lobbied by agriculture as civilized. Nevertheless there’s other dishes and desserts as well as lamb dishes and drinks including Aussie beer. You mix that up with american options you’d have a fun and genuine Aussie place Restrictions can also lead to curiosity to try other things. Actually we are diverse and have been a long time and why all this diversity BD is nauseating BS but we’re used to the diverse we have. Lol We don’t have Aussie food!
