What I want to know is, When did Asian women become People of Color?
To the left, anybody who is not a white person is a "person of color." The execrable and divisive phrase was originally cooked up by the usual suspects, leftists, to denote black people.
But leftists found it very convenient to label all non-whites as "persons of color." As if many Caucasian people are not dark-colored/swarthy.
Of course, there are the equally nutty alt-righters who only consider Caucasians from northern Europe i.e. Britain, Germany, Scandinavia as "white people." That would leave out Eastern and Southern Europeans, Semitic peoples, and many people from Asia Minor.
Where I grew up I had classmates and friends who were of Arab descent. They were thought of as white just like everybody else. There were virtually no blacks or Hispanics in the city where I grew up fifty-sixty years ago. It's a little different today, but not by much.
Leftists are always seeking reasons to divide people, and creating hateful terms like "people of color" is just one way.
