Take it easy there big fella  Unfortunately one part of WP guidelines is that of published material serving to advance a position is original research and its fairly obvious from the discussion above that the position youre trying to buttress is that gaijin is not derogatory  But this doesnt mean we have to throw out the baby or the bathwater at this point  The research youve done will create a great historyetymology section if worded carefully  The issue as Exploding Boy pointed out is how do we deal with the situation right now with some peoplegroups considering gaijin derogatory  Its a significant group and if we have to cite Debito as one end of the spectrum then so be it
