I have figured out who that feminist in Michigan is and why you might think she is the DU poster. But I would want to know more about the DU poster's other posts before jumping to that conclusion. Does she ever give any clues that would link her to the feminist in Michigan? Then how does the Nebraska reference fit?
More investigation needs to be done but if it is who I think it might be, this would be BIG NEWS. As to Nebraska, I think this has something to do with a previous secret identity supposedly assumed by Jeff Gannon she is referring to.
