So honestly, I could have used better words than "minority" there, for instance "disadvantaged/historically disadvantaged," "underprivileged," etc. Minority isn't technically wrong perse, but it feels less accurate than I'd like. I'd typically use minority to refer to people of non-white skin tone/culture (for instance immigrant Russians or Slavs might be white but contextually in the US culture I think could be considered a minority). It's not really about a physical minority vs majority share, for instance there are some cities in the US that comprise a majority population of minority classes (so white people are technically a minority, but would probably never be referred to as such). It can generally be taken as synonymous with underprivileged. I mean, generally as a US speaker I speak from a US paradigm. However I would still use the word "minority" to express "underprivileged class" or whatever if I was speaking about stuff going on in the UK, Europe, etc because that's the verbiage I'm used to.
