I remember that class I took in college, where a world-famous math professor stood on stage in front of 300 people writing small numbers in chalk (which he stood in front of), while muttering and whispering in some Asian language. Then he'd stand to the side and say, in broken English, "Well, you know." And then he'd erase it all.
This topic is much the same, I think: People assume that the person with the most knowledge ought to be teaching it to others. One person has perfect knowledge but can only effectively transmit 10% of it; the other only knows 80% of the material, but can really teach 100% of what he knows. Which is the better teacher?
Here's an interesting question: erase everything you know about firearms, and pretend you were starting from scratch. Furthermore, pretend you'd grown up to be fearful of - and intimidated by - firearms. Where would you start? Whom would you ask?
With firearms, as with everything, we see everything so clearly from our perspective. Active recruitment to pass on a lifetime of safe firearms enthusiasm means that we look at it from the other man's perspective, and ask if we can make things more available, and less intimidating, without sacrificing safety.
