`:: The use of different pronouns for Angel reflects life.  When someone choses to identify as a different gender, their community, friends, and family all have different degrees of ease in switching pronouns.  The same thing happens when someone changes their name.  Some people manage it quite easily, some don't.  Some try, but forget sometimes.  If Angel were not fictional I would advocate using female pronouns.  Because she is fictional, I would suggest continuing the ambiguity.  If someone feels comfortable refering to her as ``her``, dont change it.  Same goes for refering to her as ``him``.  Hopefully the result would be the same mix that occurs in the story, with different characters, and sometimes the same character at different times, using different pronouns for Angel.  `
