I haven't changed mine at all. The purpose of the 2nd amendment was not to enable to overthrow the government but to prevent that from happening. Pretty big difference.
One of the basic problems here is that the simple fact that some crazy people who are not bank robbers or thieves in the night are killing people by the dozen and that fact is being ignored. The fact that there have been killings in schools bothers some people. Yes, we could have policemen in those schools (who would probably be the first to be shot and some schools have them anyway), if you don't mind a police state.
All this discussion over what an assault rifle is sounds foolish to someone who knows perfectly well how quickly they can be fired. If you don't know, find someone who has one and just see how fast you can empty the magazine. That discussion is up there with the magazine/clip discussions. And another thing, your arguments would go down a little smoother with the non-believers if you toned down your mention of tyrannical governments and rebellion.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
