Nick Hoffman has two mistakes.

His first mistake was
1) putting words into my mouth, then
2) calling me a liar

His second mistake was denying the vaslue of the lives of the millions of people killed in recent historical times by impact event. (What I mean by "recent" may be seen in the list above.)

While some impacts are merely suggested by written data, and await detailed confirmation from field geologists (and I hope that money for this comes from NASA's Mars budget),

It is known with certainty that very many people were killed in the Rio Cuarto Impact (3rd millenuium) and by the Great Wall of Water tsunami in Australia (ca 1500 CE).

Hoffmans statements trivialize the deaths of at least several hundreds of thousands of people, and the total casualties due to climate collapse are likely to have been in the millions.
