LL, I don't disagree with you, but I've also moved on from tilting at that particular windmill.
you can't force people to "get it". Few, if any, of us did right out of the gate. There are too many variables in terms of why people *really* get into this stuff vs. why they say or think they do. The guy that says he's looking for a "home defense" firearm is more often than not looking for a hobby, something to waste extra income on, and a social group to belong to. So railing on that guy to "go take a class!" (as I certainly used to do) is pointless.
What we can do is encourage them to get out and shoot, regardless of the venue, regardless of the application and (almost) regardless of with whom. it's the application of the trinket that changes hearts and minds. I know that, for myself, I got into IDPA because I was going through a breakup, which in turn led to training classes because I met people at IDPA that hosted same and because I realized how much I sucked only when measured against others, which in turn led to changing my perspective about firearms, their use, their application, etc.
of course, I've subsequently realized it's 99.9% horseshit and the remainder is horsepiss, so I may not be the best example...
