Yeah, its a little like a modern person such as you or I trying to imagine how someone could have ritually slaughtered animals and children to placate an angry earth shaking God.
No matter how much of an effort we make to try and imagine or empathise ourselves into that role we KNOW about earthquakes, tetonic shifts, natural disasters and we KNOW about superstition, we're forever different as a consequence.
For all the people interpreting ancient greece in one way there's others interpreting it in another, for the people who consider the urns with acts of "boy love" on them and consider it to be some sort gay men's utopia there's other interpretations which suggest its a taboo, as in "you simply mustnt do" or "the next villa are bastards, they rape their kids".
Similarly much of the historical appraisals of earlier or historic societies from earlier times, such as the nineteenth century when considerations of orientations arose (Peguy is that the Psythopathia Sexalis - spelling- you're talking about?), where highly prejorative, villifying sodomy and seeing it as an act of violence or domination. At least the sodomy as rape and never a consensual act is something they choose to focus upon, such as the rape of surrending chieftains by Roman generals.
