What IS good, and how do we determine it?

No need to go all hypothetical since this very scenario has taken place.

War bride is a term used in reference to wartime marriages between soldiers and foreigners, especially–but not exclusively–during World War I and World War II.

One of the largest and best documented war bride phenomenons is American soldiers marrying German "Fräuleins" after World War II. By 1949, over 20,000 German war brides had emigrated to the US.[1] Furthermore, it is estimated that there are "... 15,000 Australian women who married American servicemen based in Australia during World War II and moved to the US to be with their husbands"

No the soldiers aren't "rapists"....

And if they did it to all the women, not just those who chose to emigrate, on the basis of their virginity, would your opinion change?

Oh, and also, does the stubborn sophistry with which you insist on conducting yourself really seem worth the insane hit to your credibility you take every time you open your mouth? Because congratulations, you managed to delay having to answer the real contention of the post, that you have no answer for, for a whole one post.
