People with little or no experience with firearms use them to save their lives far more often than they hurt themselves or someone else accidentally. Basic gun safety is not rocket science. Not everyone is as enthusiastic about proficiency with armed self defense as we are. You don't have to take classes with some gun guru or even have tactical training in order to safely and effectively protect yourself. Yeah, I have training and I train regularly. Because A) I am in a situation which increases my odds of needing it and B) I enjoy it. Should we mandate that this criteria be applied to anyone who decides to buy a firearm?
If someone wants to post some factual statistics on how many "untrained" first time gun owners cause harm to themselves or others I'd like to see it. I'm going to take an educated guess that the number is lower than the number of crimes committed by people with AR type rifles, and every single one of us here uses THAT lack of statistical significance to vocally oppose increased regulation and outright bans on "Assault weapons".
I think rather than admonishing people for deciding they need a gun and complaining about how stupid and potentially dangerous they are we would all be better served to help these people understand the ramifications of owning or carrying a gun for self defense and show them how to do it safely. Welcome new gun owners into the fold, they could be helpful allies in combating the onslaught of gun control laws. All these sort of attitudes and conversations do is lead down a slippery slope which ultimately dilutes and erodes the strength and meaning of the second amendment.
Personally I would prefer complete, unrestricted 2A rights to the litany of ridiculous gun laws we have now. Does anyone here actually believe that laws prohibiting felons from owning guns actually keeps felons from having guns? Last time I checked the second amendment didn't require you to have some sort of government mandated training to exercise your rights nor does the phrase "except some classes of undesirable people, to be determined later by lawmakers and public opinion" appear after the word "People".
