The twirling of the lariat is the hardest part to master, because many people have a hard time learning how to make the twirl happen with their wrist. Move only your wrist, not your whole arm. Think of your wrist as an axle, as if the rope was a wheel revolving around your wrist.
Aushwitz killed over a million people by the end of WW2, and was one of the worst camps to be sent to during the war. The pure evilness of that went into these killings was shocking, and children were often subjected to the worse of these tortures because they could not defend themselves.
Many people think they know the story of Auschwitz. It's the place where Jews were murdered. End of story. But for nearly the first year and a half of its operation, there were only a handful of Jews sent to Auschwitz. Its main purpose was to house Polish political prisoners and then Soviet prisoners of war. It had nothing to do with the mass extermination program. But you can only begin to understand why it evolves into an extermination camp once you understand how it goes through this phase of doing something completely different.
