Very well done and thank you for this outstanding contribution.
I would add one thing:
The Constitution regulates the conduct of government, not that of private persons or entities. Nothing the corner store, you [non-governmental] landlord or your [non-governmental] employer might do (even if illegal for other reasons) can be unconstitutional, because their conduct is not subject to the Constitution.
"It is long been a principle of ours that one is no more armed because he has possession of a firearm than he is a musician because he owns a piano. There is no point in having a gun if you are not capable of using it skillfully." -- Jeff Cooper
