I feel like you're just arguing I argue. I can't imagine how much of a joy you must be to talk to in person. When a justice says "commonly owned firearms for any common lawful purpose including self defense", it does tend to indicate semi-autos are protected under that ruling. It's not whether I agree or disagree, it's reading the ruling and applying basic logic.
Nonetheless, I'm done here. It's apparent you just want to argue for the sake of arguing and basically just want to go down the "no!" route. And that's fine. That's your perogative. Personally I think the longer we stick our head in the sand, the faster the anti-gunners will make the rules for us.
You may be fine with it coming to the "from my cold dead hands" scenario, that's fine. I'm trying to avoid that.
