When multiple lines of evidence, from different fields of study converge, and paint the same picture, you have to accept the facts. That's why I'm stunned at the inability of most people to recognize the patterns that are playing out in our country now. Those who don't learn from the past are condemned to repeat the same mistakes, again and again. This is blatantly evident in the liberals quest for a socialist society. Yeah, like that's ever worked out in the past.
