So basically white and PoC mean privileged and unprivileged.
In a sense, yes, but also no. The construction of "whiteness" is definitely associated with dominance in American and European society. It is a power class for sure. However, by virtue of intersectionality, while being white affords you some privilege, it doesn't mean you can't fall under some power relation (your gender, sexuality, gender identity, etc. can also be involved). As well, they aren't the only racial subjectivities around, making things a bit more complex. So "privileged" and "unprivileged" are not really a useful way to think about power, and not really how privilege is meant to be used. When people like SRSers talk about privilege, people are not being firmly divided into "privileged" and "unprivileged". They are talking about what particular subjectivities afford to people within their societies, both negative and positive. A white woman in America has privilege due to her "race", but at once is subjectified by her gender. A burakumin man in Japan has these flipped, though he would fall under different racial relations than what we have here ("white" vs. "PoC"). Privilege is also not a net score or anything like that. The privileges afforded from being white in Western (note the capital, not the western hemisphere) societies are very different from the ones afforded from being a man, hence why they are on different axis, though they still
interact
(as in, it's not simply addition either, a black woman has unique things to deal with compared to a white woman and a black man added together). I hope this isn't too much, but I really wanted to get across what privilege actually means, as there is a lot of misinformation out there.
Jews face diverse situations where they can fall into the former, latter or somewhere in between, based on whether they are ethnic, religious, or both. Am I following correctly?
This is more on point. Relating to these
particular
subjectivities, this is absolutely correct. While Jewish people are usually defined in terms of a different set of racial subjectivities than what "white" and "PoC" can define, they can be affected by these subjectivities, as people in America society use them to define race to a certain degree, though not entirely, otherwise anti-Semitism wouldn't be a thing, hence the importance of other racial subjectivities. However, the existence of the racial subjectivities of white and PoC and discussion around them almost inevitably means that society will attempt to define Jewish people along these lines. In fact, this very post you've made here today is evidence of that.
I hope everything here is pretty clear, as this can be a pretty complex topic when you're going beyond basic details.
