So I'm either not literate, not engaged, or not people?

I'm surprised to learn it is as common as USA, UK, and EU.

Technically you're one or more of those things.

Either would indicate one of two options. (Common usage proponents, keen to reduce nuance in communications, notwithstanding.)

Seems about as important as knowing FRG = West Germany, and GDR/DDR = East Germany in the 20th century.
