Why is that a *double edge sword? Seems to me it only cuts *one way.

Well, insel...it seems that as victory girls they were praised for spending their time with servicemen, that it was noble and patriotic to mingle with and date the boys to lift their morale; but then, in another breath, they were denigrated as patriotutes for dating servicemen, and as a bad influence on the boys. A real double standard.
