I've been re-politicized around Jewish identity as an under-represented minority ethnicity. It came from a meeting I went to. While it is perfectly true that the art world has many Jewish people in senior positions (which is the argument against Jewish culture being an under-represented ethnicity), those people in senior positions are no different from the rest of dominant culture. They do not bring their ethnicity with them, it seems. So there is an argument that the culture is still under- or mis-represented in dominant culture, despite the fact that individuals from that culture hold senior and powerful positions....
hmmm...
On a related note, I've also been re-politicized around Irish identity. Not really because there's been rash of anti-Irish stereotyping on tv or whatever (because, as I have mentioned before, I rarely notice that because I've become 'acclimatised' to England) but thinking further about what I just mentioned. Anti-Irish racism continues in a generalized undertone in English culture, but it's also invisible to most English people's consciousness. Maybe because the racism rarely becomes violent? I don't know. But there is also an argument around thinking about Irishness when we think in terms of under-represented or mis-represented, under-valued cultures.
