If anyone were to ask me what was one of the most essential “ah-ha!” tools for learning about White Privilege I would say, without pause, “White Like Me” by Tim Wise. If you haven’t read it, you’re in luck — the movie will stream for free for one month. Here are the details — http://www.timwise.org/2013/07/white-like-me-race-racism-and-white-privilege-in-america-the-movie-now-available-for-streaming/
I might add, “The Color of Fear” would be my other immediate response.
I revisit both in my personal work. Go and read them/view them.
