"I am not playing anything here at all. This is a very serious event that has repercussions on a global scale toward building safety." All the demolition theory critics have said that no steel high rise ever fell due to fire, until 9/11. One of the big details about WTC7, was that the NYFD did not fight the fire, in part due to a lack of water. This may be a bigger factor as to the collapse of WTC7, than whether the failure of column 79 or something else in the east wing, initiated the catastrophic failure. Floor to ceiling flames were pouring out east windows on the 8th? floor of WTC7. No water was sprayed into those windows, to quench the fire. Locally, the other day, there was a fire on the 11th floor of a 25 floor apartment building on Wilshire. Flames were pouring beyond floor to ceiling out of windows. From a nearby balcony LAFD quickly knocked down most of the flame pouring out, once they got a hose on it. If the fire had been left unchecked, it would have likely burned up to the next floor, as flames had already cut a hole into the exterior wall on the 12th floor. Engineers were going to check the structural integrity, but the integrity would likely have been worse, if the fire had been allowed to spread upward in the building. I have not seen your videos and thus do not have an opinion as to whether your assessment is correct or not.
