So much to unpack? Oh, you sweet summer child. Tribalism isn't just putting up a physical wall within your own claimed territory. It's beyond language, gate keeping who should be able to love one another, heck even politics, which shows that it isn't a social construct. English as a matter of language is more often used because we import/export, and the positives outweigh the negatives. And I am well over thirty years old and well before youtube, many Europeans were already fluent in English. It is easier now, sure, but its also easier to learn it wrong.

This video being a critical analysis, etc. is just your opinion. Do not do like the American echo bubbles and confuse opinion with fact, due to poor education on the matter.
