It doesn't matter whether Chauncey DeVega are right or not. The moment she decided to use the term "White Privilege", the discussion are over and the name calling have begun.
White Privilege is a really useful concept, IMO- it represents a phenomenon which definitely exists in our culture. I'm not quite sure how it functions as name-calling- explain?
Whether the concept are useful as theorectic construction are a lot different than whether it's a good idea calling people out for it.
It's always a good idea to ask yourself whether the thing you believe are a result of social advantage. Do I not care about abortion because I'm a man as example are a good idea to ask yourself.
But when you say other people only believe the things they believe because of a social advantage, it's pure name calling, no different than calling people racist, volvo driving latte drinking liberal, unpatriotic etc. It's the argument of people who are not willing to back up their argument, but try to silence their opposition by belittle them.
