I know they weren't directed at me.I don't think the comments were directed at you, or really anyone here. I know mine weren't. Simply being a contributing member here would indicate a certain amount of commitment to learning and proficiency, and you DO shoot, even if it's not as often as you'd like. Believe me, I understand...life happens!
What I'm referring to is the guy/gal who goes out, buys a gun, never even shoots it (or maybe puts a magazine or box of ammo through it just to say they did), and then never goes to the range again. They figure that all their self defense needs are now covered because they own this magical talisman that will protect them from any and all evil, simply through its existence.
Not everybody needs to be a grandmaster competition shooter or Delta Force operator, nor should they. That takes way too much time and money to leave you much of either left over to enjoy the life you're trying to protect. But carrying a gun is a commitment that requires at least a bit of effort to do it responsibly.
I like to compare it to voting...both are rights that we have as Americans, but both come with some inherent responsibility on our part to do them properly. Lots of people go in the booth and just push the buttons without knowing anything about the candidates or what their record is, or what their positions are. Doing it right requires some research and a bit of time spent studying backgrounds (even on the minor and obscure ones!) before we enter the voting booth. We're not asked to commit our lives full-time to serving in Congress, but it's our responsibility to make an educated choice about who we send. With carrying a gun, nobody's expecting average Joe citizen to be a full-time tier-1 operator, but ideally he ought to be at least somewhat educated and basically proficient if he's going to tote one around.
