“Are you saying people recently became “squeamish” about the “historical” belief that supernatural fallen angels bred hybrids? You’re saying that the historical interpretation of Gen 6 is that those were fallen angels mating with daughters of men?”
Well, perhaps squeamishness is not the best way to characterize their motivations, but yes. That is the traditional interpretation, not an innovation.
If it is the traditional interpretation of Gen 6, can you show me a paper from medieval times discussing it, or up to 1800 or so?
