As for the NRA. They are the largest supplier of firearm safety training and materials there is. I took the NRA Safe Hunter course sitting in my 7th grade classroom. The NRA supplied targets and safety training for my high schools shooting team/clubs. The training for my concealed weapons permit was NRA materials, only the parts of the training pertaining to laws and deadly force were supplied by the state. The NRA's Institute for Legislative Action (NRA/ILA) was created in 1975 as a political arm of the NRA. You won't find the /ILA on any of the NRA's materials for its original and much needed purpose. Needed because of increasing ignorance about firearms by detractors.

Just as gun owners dismiss and laugh about people going on and on about "assault rifles" (within the military there is no such designation, assault is a verb) and "clips" (only the M1 Garand had them and idiot politicians who overstate the power of M-16s by several orders of magnitude, they tend to dismiss the anti-gun Kool-Aid drinkers who babble about the NRA. In the interest of sounding like you know what you are talking about I suggest that you put the /ILA on your demonization of a gun safety organization.

If that sounds harsh, sorry, but it was to illustrate what I write next. We will never have fruitful conversations about violence involving firearms while one side (yours) is routinely dismissed as not knowing what the hell they are talking about. For the most part, they don't. Just as you dismiss gun owners and "NRA koolaid drinkers", they dismiss you as ignorant. There will never be productive discussion with that. I don't know if you watched the five YouTube links that were provided in the discussion, but I suggest them in the interest of the same issue.

Edit addition: My point is that dismissive demonization of the "other" tribe inhibits productive discussion (from both sides). The more likely result of that is the urge to tell the insulters to perform a sex act on themself with a fire hydrant. It is just ranting for their respective tribe with no hope or intent for problem solving.
