This is ignorance. Racism, yes, but a racism that is based in a kind of religious self-justified ignorance.
Philosophically speaking, it is the result of postmodern identity politics, where each individual is justified in its own experience, and everyone’s subjective experience is absorbed into the subject as a justified entity that is communing with otherness. It is a self justifying correlation of meaning that is often difficult to root out in order to cause change. For the exact reason that everything that you would want to tell the person as to what is philosophically occurring for that person, the person absorbs into a self justification of their own primary experience.
The ignorance, while indeed coming out of an individual position of subjectivity, is likewise enforced ideologically by the mistaken postmodern apprehension of identity politics￼.￼￼ Responsibility comes in understanding this religious problem, religious in the sense of postmodernity. ￼ It is less something that someone comes to terms with through some sort of change of heart. For we are then only left with the identity politics where a person is changing themselves while the system of ideology remains intact as a valid point of reference. ￼￼
This is the non-philosophical ‘radical’ responsibility.
