As a common practice, one should look at the steelman version of his opponent’s argument. Find and watch a video of wtc7 collapse from the south side, the side that had an exterior column failure because it was hit with debris from tower 2 collapse.

While the damage to the south face of the building looks really bad, it’s not structurally critical and the absence of it would not have done anything other than prolong time to wtc 7 collapse, according to nist.
