Worldwide, subtle forms of racism in higher education institutions have been becoming more diverse and frequent among students and teachers. The question is how to treat these forms in the field of subjectivity.
There are films, documentaries, plays, poems and interesting short stories which can be read out to the students. Lecturers, but those who can really make their talk interesting, can be invited to lecture. Perhaps the most useful is role-playing. If one takes on the role of the 'other' one may learn to empathize. Psychologists may talk to the bullies in the class to understand what makes them torment and lead the others. Shaming students may not be helpful but making them aware of the damage they are doing may be. History too may come in useful as the students are taught how incidents of history, not innate and unalterable differences, have created the situation in which some people are discriminated against.
It is visible with people of color, but what about even subtler forms of discrimination based on 'caste' which is difficult to 'make out'. The struggle is more on the part of the affected person.
