Although not as active as they used to be luckily, I still don't think they are big fans of keeping people of the darker skin alive. Here's some fun facts about the kkk in the past about killing thousands of black people:
Across the South, the Klan and other terrorist groups used brutal violence to intimidate Republican voters. In Kansas, over 2,000 murders were committed in connection with the election. In Georgia, the number of threats and beatings was even higher. And in Louisiana, 1000 blacks were killed as the election neared. In those three states, Democrats won decisive victories at the polls.
