You also have to remember one of the axioms of PC research - you're doing the work to confirm what you already know is true. One of the most irritating things I've encountered in the history PC community is the smug conviction that the practitioner of PC history somehow has a unique insight to truth just because they happen to be PC or of a specific gender/racial subset. By this I mean that "only a woman can truly understand Women's History", but she is somehow also qualified by this unique insight to pass unquestionable judgment on any other subset of history she happens to encounter (to include African-American History, Native American History, Political Science, and anything else she latches onto). By the same token, this "researcher" (although often of upper-middle class origins) is somehow qualified by gender or race to understand the situation faced by those of a much lower social class, whose lifestyle she may never have seen up close, let alone experienced.

Sorry...PC always gets my pulse rate spiked.
