My response to your logical fallacy:
We can prevent these kinds of citizens represented thusly from purchasing weapons easily. We could remove his and others' access and ability to legally purchase guns from a reputable and responsible gun seller forcing him yes to attempt to purchase guns illegally. I get that. But see this is the part where you lose me because that's where your side stops. You see no other options beyond – he could still have the potential to get a gun somewhere so we might as well not try anything else and just give out more guns. But see – FACTS. Facts are things which if you are a logical and reasonable person you will understand the facts are: countries with stricter gun control laws have fewer crimes committed with guns.
No other country, let alone First World country, has the problems with mass shootings perpetrated by public citizens that his one does. We don't have to take away all the guns. Yes, this is American - you, me, we all are guaranteed the right to bear arms for personal protection and hunting and reluctantly recreation. Yes, I believe that there are reasons for good responsible gun owners to absolutely own guns. What I don't see are enough responsible gun owners being responsible, purposely deciding to make a choice about legal gun ownership and to do it in a responsible organized manner. Before you can get behind the wheel of a car there is a written exam, then you have to drive with an adult, then you can't drive after night, and you finally take an exam with a professional to critique your work to make sure you are ready to drive 5000 lbs of heavy metal through crowded streets full of other people. We do this because as a society we understand that cars are weapons, that they are dangerous and that there is at least a baseline of understanding you need before the rest of the people on the streets are going to feel comfortable with you behind the wheel. We have nothing like that for guns. Lethal, deadly, capable of taking out many people at once but there is no requirement for licensing, registering, insuring, waiting, learning, educating, or research. None of it. Why are so many responsible law abiding gun owners threatened by background checks, by waiting periods, by licensing? Why would there be a problem doing research on guns and their impact? If you want to preach that not all gun owners are irresponsible then I say: Put up or shut up. There's nothing responsible about denying common sense gun control.
Hide your guns.
Gun Control. Simply be smart about them. Think about the fact that this country can't even study guns because lobbying i.e. the NRA has made it impossible. You know what else was impossible to study the long-term health effects of because big money lobbied against if – Tobacco. Hopefully, you're aware that everyone involved in those lawsuits has been found in the wrong. Much as I suspect stringent guns rights groups will be found to be.
Why shouldn't there be background checks? Background checks are famously backlogged because of so much political back and forth. But you really can't wait 72 hours to handle that gun you just popped in and decided to buy today on impulse because it was shiny and pretty and lethal? If you're telling me that you can't wait 72 hours for a background check to clear then 1) You're too hyped up to safely handle a gun. We'll re-check in 72 hours. 2) You can wait.
If your argument is that you believe that the Second Amendment unequivocally grants you or anyone else the right to own and do what you want with any gun you could ever want and multiples of them to boot then you are sorely mistaken. Firstly, when the Second Amendment was written they had single shot muskets not automatic or semi-automatic weapons. They likely never could have planned ahead for the advances in technology that would eventually be made leading to the advanced weaponry available today. Bringing me to my next point: These men were smart men who wrote the Constitution. A racist, homophobic, sexist, heathenry of men but for their time most were well educated leading them to be picked for the convention in the first place. If you were able to bring those men back to life today and you could somehow get them to look past all the other future-y shit to just sit down and listen to everything that has happened to this country over the last 200 years, somehow if they could grasp and understand our history with slavery and abolition, suffrage, Civil Rights, the Great Depression, two world wars, Vietnam, Iraq, 9/11. If you could show these men the loss but also the hope of all the people that fought through that crap to where we are today then show them Newtown, CT; and Aurora, CO, and Columbine High School. Show them the aftermath at Emanuel African Methodist Episcopal Church or Pulse nightclub. Then you tell them that it was all done in their names, under the guise of protecting the Second Amendment and I find if hard to believe that at least one of those rough and tumble ride or die American men wouldn't punch you right in the face. If you could explain to them the weaponry available today and in this climate you think they would honestly tell you that you're upholding the spirit of the laws that they wrote?
Automatic and semi-automatic weapons like the Sig Sauer MCX and the AR-15 were built for military use. Designed years after they were all dead and meant to kill and injure the masses during war. Tell them this is weaponry that you're fighting to keep in the easy to obtain hands of terrorists, rapists, abusers, and let's be honest occasionally someone suffering from a psychotic break all because you support the Second Amendment. Explain there was an armed off-duty police officer working the door at Pulse but his more practical and logical weapon for protection was nothing in the face of a weapon designed for war. You have already of course explained that the LGBTQ community is a protected community in this country afforded the same rights and protections under the Constitution that they wrote so they'll understand the implications when you tell them that a US Citizen legally obtained military grade weaponry after being offended by two guys kissing to mow down more than 100 people.
We know that there are ISIS sympathizers in this country and we know that people who feel different find solace in fringe groups who make them feel needed and wanted and a part of something. These groups fan the flames of anger and encourage them to hit "soft" targets where they can do a lot of damage. Mateen took his anger and rage with himself for probably being gay and the hate he felt because it went against his belief system he been raised in and it erupted in the very way ISIS wanted. This lone wolf angry guy took aim at everything that makes America great: partying, love, acceptance, families, inclusion. He went after what we are as a people by targeting a vulnerable segment of our population and most right-wingers can't even admit that Gays were targeted at all. Explain that to these men, that you want to interpret the Constitution only in a way that in benefits you and not every person in this country and it is my belief you'll be told where you can shove it (but probably in better language because they're from the 1700's).
We could have stopped him because we could:
-Allow research and data gathering on gun crimes
-Deny suspected terrorists from owning guns
-Deny domestic abusers from owning guns
-BAN ASSAULT WEAPONS
-BAN ASSAULT RIFLES
-Have a waiting period
-Require gun safety and licensing for all gun owners
You're right he doesn't represent ALL gun owners but he definitely represents every gun owner who isn't for COMMON SENSE. There are things that can be done but people's fear is what's stopping progress. It's always fear. No one is saying to take away all the guns, at least not me and not anyone I know. I'm saying show me you being responsible and logical. Make a push to change the gun policies we currently have because much like the failed drug war and ineffective criminal system – we don't have it right yet. Something those confused old white guys from the past are probably even more peeved about.
