Agree. And generally, ironically enough, those who are in the know tend to be white, middle-class, university-educated, while it's usually the poor, uneducated and disadvantaged who are not in the know.
And it's so hard to stand up against this stuff. I wrote something recently where I used the term "ethnic minority" and someone commented "we prefer the term 'racialised minorities' to indicate that these groups are racialised by the wider white society'."
I really wanted to point out that not all ethnic minority groups feel "racialised" by white society - indeed some are actively proud of being a racial or ethnic minority. All the Jews I know, for example, feel that being Jewish is an important badge of identity - they are not Jewish because the rest of society has "racialised" them but because it's how they see themselves. I'm sure the same is true of other minority groups such as Sikhs.
I couldn't be bothered to have the argument though - too exhausting.
