In my professional life, I got to talk to Australian academics. For curiousity and not revealing my beliefs, I asked them about gun issues. All the ones I talked to (granted a small sample), thought gun people were 'nutters'. Is that a general view. I also read that the defense against the draconian laws was not based on a RKBA perspective for the most part. It was approached as an Australian needs a 'sport'. Gun usage was a 'sport' but you could get another as having guns was too dangerous and overcame the need for 'sport'. This is an important nuance as protecting the 2nd Amend. or proclaiming one's support for it is done by nuancing for hunters, sportsman and target shooters. This correlated with the politician wandering around with a Tweety Bird killer O/U shotgun and/or shooting down the mighty skeet.
As Joe Scarborough said (ex-conservative who was blinding by the wiles of Mikka) - I don't need a 30 round clip of cop-killer bullets to go hunting with my son.
I think we have a chance to legislate protections of the RKBA for its intended use now but the current set of politicians won't even try. SCOTUS doesn't have the vote to take up a crucial case, and if it did - it probably would lose.
