Culture can take a huge part of your life in some cases, even if you want to be involved just because curiosity it might be complicated. Because different cultures have different dresscodes, callendar events and religion. And in modern society it's hard to keep up with it all, or even some of the things.
Naturally it can only affect you by so much, you might start speaking in language which is specific to its culture.
Then again culture can change, because humanity is growing and learning. Im fairly certain that even smaller groups heavily affected by culture have changed because of options that are available now that wasn't there in the past, cooking methods or whatnot.
Tbh you shouldn't force a culture upon anyone, and you can't. It basically develops itself. If you go back in history you might think it was more peaceful with different cultures but Im pretty sure it caused many conflicts and fights/wars between villages.
Im glad for new tech, internet and food. And im glad were involving in certain aspects. Music and everything else is basically offered to us not forced on us, you can either eat good food and listen to music you like or you don't.
Culture is affected by change that people involved in change accept.
I still find different architecture, different people and so on interesting even tho I eat burgers and listen to modern music.
Also I still like some traditions and traditional food, but it doesn't mean I eat it all the time because there's better stuff to eat.
