The 1 billion global number is not relevant because both the titles of the article and the post submission are about "U.S. minority" and not "global minority". The asian population at 4.8% of the USA is mathematically a minority.

>Trying to micro-categorize who is a minority in what context has to qualify as some sort of vanity.

The minority classification isn't about vanity in this case. The article isn't about Asians not represented as masculine leading actors in Western films or paraded as a prized husband-to-be for girls in The Bachelor. It's about admissions to Ivy League schools which has economic consequences. Minorities are complaining about unfairness (real and/or perceived).
