I *think* that the PI perception of the USO stems from a perception (note that I'm not claiming to be describing reality here) that they had lots of women whose only role was to be an entertainment model, keep up the troops' morale - but actually fight in the war? (Gasp, faint!)... and there is a perception that they did things in blackface, as did other entertainers of the time, and so on. At least, that's what I think Pseudolus meant. Pseudo, care to join in?
