I am afraid not. The court may have had a historical review before discussion, but they did not examine the minutes of the Constitutional Congress, where it can be read plain as day that the Founders discussed at length and intentionally rejected including a right of self-defense in the 2nd. They talked about it and decided against it. To be plain, the Framers of the Constitution did want an armed citizenry, but only for the purposes of militia, and militia for the purposes of a check on tyranny, not for crime or hunting. Back then, pretty much everyone was armed, and they wanted the armed citizenry to form militia and they wanted to prevent the government from disarming the militia. The 2nd was never about about an individual's right of self-defense. Everyone has a right of self-defense, and we do not need the 2nd Amendment to have that right. The court's decision regarding the 2nd in that 2008 case was literally pulled out of thin air, and it will only stand until someone gets around to correcting it, and it may be a technicality, but it's wrong to include self-defense because it weakens the Amendment and reduces or eliminates any check on tyranny.
The point about the Black Panthers was simply to illustrate a proper exercise of the 2nd Amendment in that famous instance at he Alameda County courthouse. Just being a gun club is not an exercise of the 2nd (in its original intent) unless that club arms themselves and assembles in such a way to put themselves' in harms way to prevent tyranny from succeeding.
