Those people were dumb and not properly trained. We should be allowed to defend ourselves.
Some people are very comfortable around firearms, and some clearly are not. Fortunately it's not compulsory that you own a firearm, so if you don't like them, don't buy one. I was brought up to know how to use one responsibly, and growing up I remember there were always a couple rifles stacked in the corner of the parlour and my grandfather had a .357 Magnum in his bedroom & a shotgun in the gun rack in his pickup, and all were loaded at all times. I would have never touched any of them, nor would any other child in my family, because we knew they weren't toys and adult supervision was required should we desire to shoot one. It should be required that anyone purchasing a firearm demonstrate that they know how to use it properly and competently. If you can't hit the broad side of a barn, it's not going to do you any good even if you manage to have the nerve to use it.
This is where we differ. I would kill to protect my child from being murdered.
I could NOT tell my baby's killer, go ahead and kill my child for I cannot kill you.
Ditto with my own life. You want to take my life, then it's on. I'm not laying down like a defenseless animal while you put a bullet in my brain.
I have no problem having a gun in the house, as both my children are also aware of how to use one responsibly. I also have zero problem shooting someone should they enter my house without an invitation. I value human life, however if you enter my home without an invitation as far as I'm concerned you deserve what you get, and if I kill you in the process that's on you. Self-defense and defense of my children and the people I love are my highest priorities in that type of situation, and I'd shoot an intruder without hesitation, and without an ounce of remorse.
If you know how to use a firearm well, it's your best option against an intruder IMO. A blade requires that you get close enough to do some damage, so useful if you're sneaking up on someone but not so effective if you have to face them, and frankly I'd prefer to shoot someone from cover at a safer distance. I had a cousin who detested guns and insisted on keeping a baseball bat for self-defense, which IMO is equally stupid as you have to get close enough to hit the intruder, and if that happens to be a man, and you don't get lucky enough to take him from behind, there's a very good chance he'll take it away from you because odds are he's got greater upper body strength. I remember my grandfather and my uncle trying to talk her into getting a handgun instead of the bat and my grandfather told her that the only thing more embarassing than being disarmed, was getting beaten to death with your own weapon.
Bottomline, whatever you're comfortable with, and know how to use well, will likely be effective for you. If guns scare you, then there's no point in owning one as you're unlikely to use it. Get a dog and an alarm system and you'll likely be fine. If you aren't planning on breaking into someone else's house then you don't need to worry about whether they have a gun as part of their home security plan. Some states have concealed carry laws, Oklahoma is one of them, however that doesn't mean the majority of people are packin', so I think your chances of being shot by some random loon wandering the street channeling their inner Dirty Harry are slim.
