According to your presentation:
The steps that Democrats would take is responsible and continues to allow for the Second Amendment. Though a high-capacity magazine would just mean a sooner reload, I see the point of pushing the idea of responsibility in society. But ultimately, these mass shooters are generally underage kids or twenty-somethings, with no criminal record, who use weapons that were legally purchased by either their parents or themselves.
Australia gives us a very good process in terms of buy-back. The first thing gun nuts will state is that criminals won't sell their guns back, but they would be wrong on two counts. One, enough of them are poor and strapped for cash that plenty enough would. And two, these mass shootings are coming out of white middle-class homes with no criminal records so this isn't really about the "criminal."
Republicans (GOP) are stuck between a rock and a hard place. They have largely seen their most cherished ideologies (NeoCon, Trickle Down, Church attendance) crumble over the last fourteen years and are clinging to threads. There's a reason voters wanted Trump (a middle finger to the world) to "shake things up." They mostly meant to turn back the clock. They don't know what else to do other than project the idea that they are leading a political revolution, while still clinging to remnants of broken ideologies that have outlived their expiration dates.
Donald Trump even shattered the ideology that FOX News is "fair and balanced" or that it isn't about political propaganda by declaring that it doesn't support him enough. Forget that "fair and balanced" always implied that the news was being presented though a political lens. Facts and truth shouldn't need to be balanced between people's political comfort zones.
NRA ideology is a part of this. The NRA has locked down the GOP to the point where even
Donald Trump boasted not to be afraid of the NRA. Just yesterday the NRA declared that Wal-Mart's newest rules are
bad for business. So even the curtains that allowed for the idea that the NRA is all about our Rights and our freedoms is finally being pulled back. So, arm everybody with a heartbeat is just more of the same "**** it all" attitude of the desperate. This is historical throughout the world. When societies see their most cherished ideas of the world come to their ends, they react negatively and start inventing enemies to blame for natural change.
