Why am I not surprised that guns are your favorite subject?
Regulations don't keep you from getting a gun unless you're a danger to society with one (I hope you'd agree that convicted perpetrators of violent crimes and people with dangerous mental health issues shouldn't be allowed to own guns). It just makes it a bit longer of a process.
How you store your legally obtained firearm is indeed your own business (depending on where you live, maybe not), but if you've got a kid in your house and you don't lock your gun up, you're an idiot who shouldn't have children. Also, if you keep your gun next to your bed and your spouse startles you, you may not be married for much longer, and you'll have no one to blame but yourself.
There's been a steady decline in accidental gun deaths, and it's been attributed to a mix of gun safety education programs (the best thing about the NRA - the only good thing, IMO, but still a very good thing), state laws regulating gun storage in homes (common sense gun laws!) and a drop in the number of households that have guns. While the improvement has occurred in every state, those with the most guns and the fewest laws continue to have the most accidental shooting deaths. (most of this paragraph was lifted from https://www.latimes.com/nation/la-na-accidental-gun-deaths-20180101-story.html)
Bottom line: I'M NOT OPPOSED TO THE 2ND AMENDMENT, and neither are people who want common sense gun laws. You do you, if what you're doing isn't dangerous to the innocent people around you. I personally prefer baseball bats to guns for personal protection - they're better in close combat (I dunno about you, but I don't have any wide open space in my house), cause less accidental damage, and have a use outside of killing people. But that's me.
