Read the case law. Read the USSC's opinions (both liberal and conservative court opinions and rulings). The plain fact of the matter is that within the legal community, there is no controversy here. The amendment plainly give the states the right to arm their own militias.

Look, I'm not saying that private ownership is illegal - or even that there is no right to private ownership. I'm just saying, (as all courts have who have addressed the issue), amendment 2 does not apply to private ownership of firearms. You want an explicit Constitutional right to private ownership? Lobby for one. It currently does not exist.
