I would like to declare a truce!
No more war by links (but I still like my links better than your links)
I will only fight with logic and reason (my armoury is limited)
So from an engineering perspective.
Two concentric tubes of known mechanical strengths (specifications should be available.
Large impacts at different levels in the two towers.
Fire in both buildings causing weakening of steel structure.
Collapse seeming to occur in sequence from the top down.
Was the heat of the fire really sufficient to cause the neccessary heat damage.
What was the likely fuel load for the fire (include combustible materials and the kerosine remaining after the initial fireball (too brief and low intensity to heat steel sections?)
Was the central core of the building severed by the impacts?
If so would it be likely to fall vertically or to the side?
Did any portion of that central core remain standing after the floors fell away?
Was there evidence of sufficient airflow to cause a firestorm
Could airframe alloy shredded across the building have combine with building steel to create "accidental thermite" producing effects consistent with the destruction by thermite scenario?
BTW
If I was to be an arsonist, kerosine would not be my fuel of choice.
