Sorry if he got your hopes up.
What is unsupportive Roscoe? Direct language from the Constitution? Court cases that don't mean what you are trying to get them to mean? Direct qoutations from some of the Founding Fathers that RKBA is an individual Right that no governing body in the US has the legal power to restrict?
The part where your argument falls apart is that you are trying to apply the Constitutional provision for government control, namely at the State level, of the ACTIVE militia, to all of us floating around out here as members of the INACTIVE militia. Sorry, but it just doesn't work that way.
And none of your quotations from racist judges trying to keep minorities in their place will change that.
