Buz, you start off by saying:
My OP and Message 5 pertain to the present rapidity of a variety of distructive disasters which is a phenomenon that has never been observed in US history.
The phrase to focus on there is "a phenomenon that has never been observed in US history".
You then go on to say:
This thread does not pertain to disasters which have been observed over the decades and centuries past.
But you have just said that your OP and Message 5 have, in part, to do with "a phenomenon that has never been observed in US history".
It can hardly be called off topic for members to ask you to examine that US history in some detail.
