My theory is that white people cause crime, since when white people have political power they force black people globally into poverty and shitty living conditions, which makes them turn to crime. What is happening now is that slowly deciling white population frees up political power that is being picked up by impoverished black people who use it to make their lives better, decreasing the crime rates. Healing is slow, but in 1000 years or so when last white person finally dies of testicular cancer, we can go back to the Garden of Eden that existed before white people were invented.
