I explained this very simply for you. I'll do so again, but just once more. If you believe we have a right to arm ourselves, but you draw a line beyond guns, then you believe we should regulate arms. So to argue any regulation will lead to a slippery slope indicates a misunderstanding of your own position. That or an unwillingness to acknowledge you favor regulation, but seek to limit the scope of it, which is more legitimate, but not something you have argued. Your last line is just pedantry.
Your arbitrarily setting the boundaries of debate. You don't get to do that. Arms are arms. If you think all people can be armed without regulation, then we must consider the arms you are allowing for. If you believe otherwise, that guns are arms, but not subject to regulation where other arms are subject to regulation, then you should establish that position, rather than dance around it using semantics and pedantic statements.
Oh its quite intentional that you refuse to admit you favor regulation of some arms. Because it is a significant hole in your illogical argument that guns are not subject to regulation, yet other arms must be. Unless you favor the deregulation of all arms? Then you would need to establish that position. What is your position?
