Max, I agree with everything you have said regarding black powder weapons as firearms. But I think that the folks who have waited to this circumstance to seek a firearm aren't looking for a weapon, they are looking for a symbol. Like the folks who have no health care background want a mask without having any desire to acquire the training and discipline to use it successfully. Or like the cargo cult folks in the South Pacific who built replica airplanes and crates, believing that this would cause other planed to land and bring tradegoods.
You might be right for many. However, the people who have reached out to me for training were not interested in symbols, they were interested in having the appropriate tools to defend their families.
