From a historical perspective, I don’t think these people in CA are having their rights limited—at least, not their Second Amendment rights—because historically, there is no 2nd Amendment right to public carry, whether concealed or openly.
Likewise, there is historically no such thing as a “Second Amendment right to own a weapon for personal self defense.”
That is not what the 2A says, or ever did—it’s something SCOTUS pulled out of their ass in the past 15 years. But since what they say becomes the law of the land, we have to try and grapple with this nonsense. I expect this CA law to get struck down because that seems to be what SCOTUS does with any gun law or regulation these days, and I honestly couldn’t tell you what types of gun regulations they think would be constitutional anymore.
But anytime between 1792 and 2010? This law would stand. And I think it’s important that Americans understand that, because it’s vital that we amend the Constitution and fix what SCOTUS fucked up.
