The hero of the beloved Star Wars trilogy is Luke. The principle dynamic is the complicated relationship between Luke and his father. Not coincidentally, George Lucas' last name sounds a lot like Luke. That's the one he identified with. George Lucas had a tumultuous relationship with his own father, and people who know him say that you can't understand the backstory of the movies without knowing that his dad was occasionally difficult but also very loving. They had a big break between them. In those movies, he's very focused on sons and fathers.

Rumors are nearly as old as human history, but with the rise of the Internet, they have become ubiquitous. In fact we are now awash in them.

A well-functioning democracy has a culture of free speech, not simply legal protection of free speech. It encourages independence of mind. It imparts a willingness to challenge prevailing opinion through both words and deeds. Equally important, it encourages a certain set of attitudes in listeners, one that gives a respectful hearing to those who do not embrace the conventional wisdom. In a culture of free speech, the attitude of listeners is no less important than that of speakers.
