Since most of us know nothing about the accident beyond the location, what sort of 'constructive debate' might we have?
You want to discuss stall/spin, of course it's an important avaiation topic (after all avoiding stall/spin is vital), but we have absolutely no idea if it was a causal factor, something that happened way after the aircraft was doomed or something that didn't occur.
The idea that it might have been seems to be based on a possible interpretation of what might have been seen by a witness who isn't (so far as we know) an aviator.
