One time, I heard a Jewish guy say the before the Nazis turned up the heat in the 1930s, Jewish pessimists went to New York and the optimists ended up going to Auswitch.
As a Christian, I find my faith makes me an optimist but only in the things I control and it may me a pessimist with things I don't control.
My guess is wayward Jews would have been dismissive of impending danger from the Nazi regime as they were probably less religious and less inclined to think things through.
Another trait I associate with people of little faith is they don't see the past in a glass half full way but they see the past in a more negative light and so they favour change that they think will make things better.
Thoughts please.
