One of the more popular definitions of racism of late is this: 'prejudice + power'
This makes sense in lots of contexts, specially in US
But it leads to people saying X group can't be victims - but theres lots of different power networks. Not every structure is a national or professional one. Like the poster above who experienced anti white racism in a predominantly Asian town, or workplaces and schools, even families.
In group and out groups are a feature of every human society, from your dd's class to massive countries. Race is not always the fault line, but there is always a fault line. I really cant see how adopting current US style identity politics helps at all. If the goal is to get rid of racism, we need to channel our tribal urges into more harmless directions. Not endlessly point to differences rather than similarities.
