Course claims objectivity is a white mythology.
That would imply their course is totally subjective.
Yes, and because it’s totally subjective, everyone must get an “A” in the course because everyone’s ideas and opinions on the subject are equally valid, since there is no standard that can be used to judge them. Even the student that skips all the classes, hands in no coursework, and misses the final must get an equal grade, since his opinion that the course is not worth the effort is still equally valid in a system with no objectivity.
