How could you? No one else does, and I'm not even sure that he does either.
All I can deduce from his posts is that he loves the draconian firearms laws his own state of California imposes on it's citizens and doesn't want any interference from the SCOTUS that might infringe on CA's spurious "right" to ignore the 2nd Amendment. He wants to make us believe that Madison didn't intend the 2nd to protect the right of ALL law abiding American people to keep and bear arms, but only intended it to protect that right from the feds for the benefit of those people whose state "allows" them to have guns. No state can "allow" or disallow people to exercise an unalienable right, it can only deny that such a right exists. A right is not a right if a state can allow or disallow it to it's people, it has then been made into a privilege.
Predictable ignorance.
The Second Amendment has NEVER invalidated any of those laws. Our state Constitution has though. Like when then Mayor Diane Feinstein's municipal handgun ban was overturned.
