You know he touches on an interesting point purely by chance.

Being considered a "citizen" of a country is different across countries. A country like Japan, you are born Japanese, it is not a mantle you can assume. Weibo's will always be Weibo's, regardless of how long they've lived there, who they've married or what they speak. "Japanese" is something you are born into.

Other cultures are value based. "American" is a label you can assume by moving there and taking on the values. When globalists shill for open borders by saying "America is a land of immigrants" they're actually right. But merely being in America does not make you American.
