Good luck with getting Mojave to answer the individual or collective right question. I tried and he continues to dance. He’ll probably remind you (like he has all of us) how low-brow you are compared to his supreme intellect.
The individual or collective right question is generally irrelevant to the question at hand. At issue is whether the words "shall not be infringed" means (as mojave suggests) "shall not be infringed by the federal government but may be abrogated as the state government sees fit" or whether it means "shall not be infringed" (as the period immediately following the word "infringed" indicates).
