Or perhaps put something in about a militia, but one that was well regulated.
You are a militia member.
Unless you are not an American, I am not creating a hypothetical scenario; I am stating that under the constitutional meaning of the term, you are a militia member. You may not be one for which Congress has created an obligation to register with selective service. You may not qualify under Congress’s rules to be drafted. But under the constitution, Congress can use their powers over the militia to compel you to act. You. Are. Militia.
When you insinuate that the Militia is not “well regulated”, what additional regulations do you wish to be subjected to?
Personally, I think every member of the militia (Every American) should be required to attend a class on the laws governing use of force. Not enough people actual understand them.
