See, that's the beauty of it -- I don't have to.
He argues that the 2nd protcts certain weapons - RPGs, etc.
For that to be true, they cannot fall under the "dangerous and unusual weapons" category as proscribed by the court. Since he made the claim, the onus is on hm to show that they do not fall into that category, whatever it may be.
Thus, its up to HIM to produce the definition; he then pleads ignorance on the issue, thereby ending any effective conversation on the point, as he necessarily cannot support his assertion.
I wold be -very- interested to see how RPGs, etc, are not "dangerous and unusual weapons" under the context oif this decision. He knows he doesnt have a prayer at showing any such thing, and has run away from it.
But then, he doesnt really want to carry on a conversation here, he wants to deflect and misdirect the conversation towards a straw man that he can beat up at hs leisure.
