I grew up in a Christian country and your "some" is doing a lot of work. Sure, perhaps some specific Christian theologists take that view. But, all actual Christians are taught from childhood that it was one specific man, tempted by one specific woman into eating a literal fruit. The only thing that's generally mentioned as open to interpretation is whether the fruit was an apple. You might get exposed to more nuanced theological views if you study at a seminary, but not while living your life as an average person who identifies as Christian, which is the vast majority.

I was raised Catholic (mass every weekend, CCD through 8th grade) and not once were we ever taught your interpretation. It was Adam and Eve, one man, one woman.
That is such a tiny minority I’ve never even heard of that until now
This implies there is a small minority, i.e. human suffering not down stream of human decisions - what about that?
I actually don’t want to argue, I can understand that for some people disregarding that part or finding an explanation is enough and still helpful.
My point is to highlight that, similarly, for others, this idea and its interpretations are unhelpful.
