Open carry in Oklahoma

DC doesn't count?

It would count if it had banned all guns or even attempted to, but it hasn't so it doesn't.

Members of legislatures have proposed bans.

Name one.

Just because it was rejected doesn't mean the threat isn't real.

You have to cite the attempt first and make sure it has all the specifics that would ban all guns.

Are you saying the quotes from that site are all lies?

No, I am saying Kleck is a frequently used source but has been known to simply invent crazy "facts", I am also saying that nothing there backs up the claim.

That one of the founders of HC/Brady said the ultimate goal was exactly that?

Look at the quote you posted, it doesn't even say anything like it.
Now if that quote said all guns then you might have a point, if it said all guns without exceptions then you definately would have a point, but it certainly doesn't say that, so all you are left with in that link is that single quote from a nobody in Florida.
