This is off topic, but…

Heads up, people. The 9/11 Troofers are going nuts over a Beijing building fire in which the building did NOT collapse. (Google “beijing fire wtc”)

If you come across this, my suggestion is to say “Every day buildings burn without collapsing. Why did you wait until now to point to one? I’m not sure what difference one more makes. You could have pointed to any building fire a year ago.”

This drives them nuts.

Eventually, through the Socratic method, you may get them to agree that sometimes burning buildings collapse and sometimes they don’t, depending on a lot of factors. At that point, the argument is easy.
