Indians owned slaves? Did I sleep through that history lesson?

There's a story in the news about a vote in the Cherokee Nation to change their definition of citizenship, restricting it to descendants "by blood." The story goes on to say that this change will cut off the descendants of blacks whose ancestors were slaves to Cherokee owners. What? Wait a minute, what?? Indians owned slaves? Here you can learn much about what the Indian learned from the European settlers about keeping slaves, and how they adopted the practice. You think you know your history, then something like this pops up.

There's a new show coming out on the BBC that will represent the global-warming-is-caused-by-the-sun theory. Titled "The Great Global Warming Swindle," it it set to air March 8. It's directed by a guy named Martin Durkin, and he says

"It’s very rare that a film changes history, but I think this is a turning point and in five years the idea that the greenhouse effect is the main reason behind global warming will be seen as total bollocks."

For those who speak American rather than English, bollocks can be defined as "a general expression of dismay" and it refers to just what it sounds like it refers to.
