Cheers for the corrections. I replaced interracial love with love against social expectations in my post above, and included an EDIT that explains the edits (so that the comments that follow don't look out of place). Everything I said still stands. The meat of the matter is love against social expectations and the contrast between subjective/objective realities. Let me know if the corrections work. If there are still mistakes in the post, also let me know.
I don't currently remember WHY it was against social expectations, but it doesn't really matter.
the conflict that lead to the destruction of the village was about a narrow minded coward who was the village leader with clearly conservative view on marriage and social roles of women.
I am sure that someone who holds the "narrow minded coward"'s opinions is not going to see it like that. You obviously believe that the couple is in the right, but to me it is not that clear. Going against social expectations is not right-by-default. It is a clash of interests. At any rate, their love was the catalyst for the destruction of the village (a catalyst is something that sets off a series of events, and it is a concept from Chemistry. The catalyst is not necessarily to blame. Maybe it is, maybe it isn't).
Also, see below.
Uhm, i don't think it is preach against racism (or xenophobia to be precise), or "love wins all" trope.
There were several participants in events preceding the curse and quest shows how each one(including the girls in love) can be blamed without favouritism.
I think it was clearly a "love wins all" trope when Tiressia (or was it Falchos?) gave her little speech at the end about how wonderful their love is. That's how the couple sees it, at least. Upon closer examination, it just their subjective reality. And that's the part, that contrast between the subjective and the objective (the objective being a ghost village), that I consider genius.
Yes, I remember that I was given the chance to point the finger and explain myself at some point. I didn't try all the options to see all explanations, I will have to do it in my next playthrough.
