You are aware of this, right?
Yes, in answer to yo ur unrelated snotty question.
A material number of people made an intelligent assessment of their situation and decided to remain behind.
I presume your ethereal number does not include the 50,000 plucked from rooftops, pulled out of attics, and picked up from tiny land plots amid flood water who did not make intelligent decisions in the face of grave danger.
When you take things out of context to start an argument, your position would carry more water with tighter numbers than "material."
Here is the context:
“The evacuation from New Orleans was a nightmare so people didn’t leave for Katrina.”
If EVERY ONE of the 50,000 rescues you mentioned came from New Orleans only, that would still mean that close to 90% of the population in NOLA either did evacuate or else never required assistance. If those rescues were spread across several parishes, it would only push the evacuation/self-rescue percentage for NOLA even higher. This is why I call it a myth that “people didn’t leave for Katrina” — even as I repeat the critical point that leaving is not the gold standard of prudence, as circumstances vary widely.
And kindly spare me the personal insults; I have not been rude to you.
