Christianity and Hope in Madoka and the Model Minority
In the model minority, the structure forced upon all East Asians by American racism, hope is a silencing force. The younger generation allegedly gets all the opportunities the older generation had to suffer for—and therefore must also suffer to maintain what their parents accrued through suffering in an endless cycle. Have hope: Keep your head down, assimilate, and don’t complain and you will be given the scraps of whiteness, we are told. Should you resist, whatever hope you have will be revoked, and you will be treated as an anathema: the yellow peril, the foreigner.
