That obviously makes sense, but I was trying to get away from the verbosity
of:

    inSRC = set([])
    inSRC = set([])
    inEB = set([])
    inWP = set([])
    SRCfem = set([])
    EBfem = set([])
    WPfem = set([])
    SRCmale = set([])
    EBmale = set([])
    WPmale = set([])
    SRCun = set([])
    EBun = set([])
    WPun = set([])
