The statistics are clear on wars and violence. People just don't get the right image because information is much more free these days. The eighties is remembered as a peaceful era by many, but when you look at the numbers of people died in wars, through terror, famine, assorted violence, it is easy to see this is a vastly different time, and for the better.
If you had to live in any time in out history and wouldn't know the colour of your skin and gender, this would be the only sane choice. Hopefully our future is better still in this regard.
