I note a language barrier, and of that I am saddened; however you have yet to discount the fact that two Ph.D. holders have coined the phrase, in a recognized publication.
At the obvious risk of argumentum ad nauseam, and as per their book "Sexuality and Gender in Postcommunist Eastern Europe and Russia"
Quote:During war times, 'women favored voluntary rape in order to avoid ongoing ...
That is not a reference to ethnic cleansing per se; it's a reference to women making a specified choice.
Further, that the phrase voluntary rape is recognized by, at the minimum, two Ph.D. holders in the appropriate fields of Sociology and Psychiatry, is also a matter of record.
Further, as previously noted, is it also used in the book "John and Postcolonialism: Travel, Space and Power By Musa W. Dube Shomanah, Musa W. Dube, Jeffrey L. Staley"

Should you be inclined to make your case, I would ask you to do so in such a fashion as to argue against the quoted author's acceptance of the phrase.
Simply repeating, that to you, the term has no validity does nothing to substantiate your viewpoint.
I see the term as having meaning in the context of the lesser of two evils, which if I have assessed the author's meaning, they would concur.
My views on rape are a matter of record.
