Clayton Cramer has a lot of links to scanned colonial laws that show that every colony required most white males to own a gun upon pain of substantial fine. In 1636/7 Massachusetts even required people to bring their guns to church.
Apparently these laws didn't cause mass shootings, so why restrict gun ownership now? It's almost as if the anti-gunites think the results would be different since it wouldn't just be white males anymore.... Personally, I trust members of all races of either gender to carry weapons, until a given individual proves otherwise.
