I think it's a pretty cool try. It will raise the dander of a lot of folks, but some people might think a little bit about it.
I didn't really have a clue about white privilege until about twelve years ago when I was taking an English class out of sequence at community college in rural Kansas. One day our instructor was late to class because he got pulled over on the way into town. There were several black male athletes in the class and someone asked the instructor if they searched his car. I was surprised to learn that day that the black guys in my class thought having one's car searched was standard operating procedure for a traffic stop. They were surprised to learn that it wasn't.
I know I still don't have much of a clue about racial issues and I know that I still have ingrained racism, but I think it is easy for white people to underestimate the impact of racism on minorities in the US. The statistics on a bunch of quality of life issues make a pretty good case, IMO.
I'm not sure what the answer is, but awareness is a good start. That way if people are just doing stuff in ignorance, they will make an effort to cut it out and maybe recognize it when they see it happening and speak up.
Anyway, here's a blog post by a favorite sci-fi author of mine explaining privilege in gamer terms for anyone interested. I haven't searched the forum to see whether or not it's already been discussed. If it's please disregard.
