Sebastian, writing at Shall Not Be Questioned, offers a useful survey of the forces currently being marshaled against the Second Amendment and the rights of US gun-owners. I won't reproduce it here, but I urge you to click over there and read it for yourself. I think it's important.
The common theme here is demographic trends are catching up to us. Bloomberg’s money is by far the biggest factor. There isn’t enough passion for gun control out there for it to self-organize, but if money is no object, and you have a lot of smart Obama people who suddenly found themselves out of a job and needing a cause, you can accomplish quite a lot with a top-down approach.
It's hard to disagree.
Personally, my primary argument in favor of gun ownership remains fairly simple.
Says it all, doesn't it?
