It does seem to be a trend.
And part of the trend is to delegitimize the people,,call them labels and names. As if it couldn't possibly happen to the people who are complaining.
What I think people forget is that folks in NO have lived there for ages and ages with no great flood. Just like in California,,they settled there, families and ties are there. People who are old timers don't move on the threat of a disaster especially if there are long ties to a place.
My family has been here two hundred years, not in NO luckily. But I know people who have had generations of people living in NO, it is home. They don't leave easily. This time I do think alot won't go back home, home won't be the same.
