Admittedly, complexity is frightening and can be disheartening. The fact of modernity is that it is radically complex, shot through with contingencies of every sort. There are those who don't respond well to the contingent nature of late modernity and long for some sort of simple silver bullet, simple solution...these people often become "fundamentalists" of some sort as a reaction to a world that no longer makes sense. The most obvious cases of this are in societies that got dragged into modernity by globalization in the past century or so. Those societies often have a deeply reactionary group/groups in them that are frantically trying to stop the world because they don't like it and don't understand it.
No. I don't think people should be suspicious of Tim Wise's motives. And I have used his work many times to get folks thinking about skin privilege. In addition to that, I've seen the difference that suddenly problematizing the invisible can make in how people think and behave. I firmly believe that people need to do the research, do the reading, do the listening and take the complexity into account rather than reducing things to unproductive, stultifying binaries. I'd rather trust Wise, who understands what he is talking about and has done the hard work of introspection and critique than trust someone blindly spouting some sort of racist dogma (a charge that I do, indeed, level against you with the evidence of this thread), be they any color whatsoever.
