A lot of interest in someone dead for so long. Surely, lots of other people died at the same time, ordinary people who did not hear voices, who did not take up arms, who did not wage political war, people who lived quietly and who worked hard for life and family. Clearly, if she actually heard those voices, she was every bit as insane as some have claimed. Maybe it's time to de-mystify the past and, where possible, see it the way it was.
Those people aren't interesting Joan was. She was a focus for change in her time. Why waste resources on someone who did nothing when you can focus resources on the important. Your attitude is very Liberal in that regard.
