I don't give a crap whether people carry or not but that is ridiculous. Some objects are inherently more dangerous than others. That's why we don't let children play with razor blades or loaded guns. You can't hurt someone either intentionally or accidentally with a shovel at 100 feet.
A good number of people die every year running a shovel removing snow from their driveway. Doubt there are any reliable statistic as to how many but it's quite common. There is danger and risk all over - and the risk of being a gun owner really isn't much higher then all the other random **** that can happen.
So yes letting a 3 year old play with a loaded gun would be dangerous, just like letting a 3 year old play next to a swimming pool is dangerous (one died in a pool in my backyard about 3 years before I bought this house). A swimming pool isn't an unacceptable risk to most folks though just as a firearm is not an unacceptable risk to me either. I personally believe in my situation it reduces other risks resulting in a lower level of net risk. But that's hard to weigh
If we dig into this a bit more...
We lose about 550 kids per year (0-10 yrs old) to residental swimming pools, and considering how there are only about six million residential pools, that means for about every 11,000 pools one child dies per year.
If we look at guns, we lose about 175 per year (0 to 10) as a result of firearms. With something like 300 million guns in this country. For about one in every 171,428 guns a child dies each year.
Both are quite dangerous and smart parents are afraid of both. But many anti-gun folks would be perfectly OK with there being a swimming pool in the backyard versus a firearm in a locked safe (which reduces the risk dramatically).
I'm not saying that a gun isn't dangerous - nor am I saying we shouldn't have swimming pools. I'm just saying that people get let their political opinions and beliefs distory reality way too often.
Now a gun might one-day save your life (not that likely, but it could). It's probably not that likely that the swimming pool is going to save your family (but perhaps by providng a source of exercise)
Based on what I've seen - those that grew up around firearms believe one thing and those that didn't beleive the other. I've seen people that can't even sit in a room comfortably if they know there is a gun there. Just the thought of that gun in the room makes them extremely nervous. It's interesting.
