Sorry, it really made no sense to me what the two things had in common. You pretty much had to have guns to keep slaves, though. Well, except American Indians had some slaves (more like indentured servants won in wars, I gather), but they kept them from running away somehow.

Anyway...
The constitution was written after the US War with Britain, which was won by a militia including a bunch of regular guys with guns. That's the frame of reference.

So I'm sorry I jumped on you, Sandy. It just didn't seem logical. Lots of thing don't, these days.
