Someone ask the idiot if he understands the middle third rule.
That should puzzle him.
For the rest of you, it's not hugely relevant but will show his ignorance. Essentially what is says is that the moment the centre of gravity moves outside the middle third of the structure's width, then it will be unable to take the loads and collapse.
Such collapses are invariably straight downwards. Why? Because the change in the centre of gravity and thus the joints/connections/whatever means they exceed design capacity and fail.
Generally.
