Well, it shouldn't need that much "interpreting". It clearly states it is about arming a militia. A militia is a trained, organized, fighting force. To ignore that in favor of trying to "interpret" it to mean otherwise is to still pretty much ignore the first part of the Amendment.
And we know that this is what the "founding fathers" meant because they wrote more than just what's in the Constitution in this regard. They didn't trust centralized government (remember the Articles of Confederation whereas we had what was more like 13 countries versus just 1), and they felt that state militias would mitigate against the threat of federal overreach. It was not viewed as some sort of intrinsic right that all Americans could own weapons, and many SCOTUS decisions since the Constitution was written and first amended upheld gun and weapon restrictions both in terms of type and who may have them.
