Part 7/10:
The speaker criticizes what they see as ignorance and lies propagated by "stupid people" who dismiss scientific facts. They point to examples like the Tacoma Narrows Bridge collapse, comparing it to the WTC destruction, to illustrate their point about structural failures and conspiracy. They reject the idea that fires alone could have caused such collapses, emphasizing that fires can only soften steel, not melt or destroy it outright, especially in the windy conditions at the time.
