How do they disagree with me?
On just about everything you've said so far. For instance, NIST plainly states that fuel oil fires from the emergency generators "did not play a role in the collapse of WTC 7. The worst-case scenarios associated with fires being fed by the ruptured fuel lines (a) could not have been sustained long enough, or could not have generated sufficient heat, to raise the temperature of the critical interior column to the point of significant loss of strength or stiffness, or (b) would have produced large amounts of visible smoke that would have emanated from the exhaust louvers. No such smoke discharge was observed."
NIST does not attempt to account for the free-fall of WTC 7, period. NIST does not attempt to account for the free-fall rate of collapse of WTC 7 with any mumbo-jumbo about the interior disappearing.
NIST does not attempt to account for A36.
And NIST's hand-inputted computer simulation does not resemble the drop of WTC 7.
So far I have only seen you not understanding their work.
Quote whatever you are referring to I have demonstrated a lack of understanding about.
