I think it's far more a cultural trait that is pervasive in Europe and North America. The Japanese, on the other hand, are far more likely to be motivated by shame than guilt.

In my opinion, the concept of 'white guilt' is intended to shame white people and has little to do with actual guilt. Guilt is about what you did and shame is about what you are. Clearly, 'white guilt' is about what white people are, as an identity, and not about any individual white person's actions.

Wokeness is all about obfuscation of meaning. You can never take wokeisms at face value.
