I do think that Armandhammer has a point in bringing up Atreyu. I think we've become a lot less willing to accept and mentor minors, even the responsible ones, as a result of that incident.
I'm not saying we should have wholesale acceptance for minors, but we do need to come to terms with the fact that the demographics of airsoft in Canada is something of an aberration. We can exclude minors because of our legal circumstances, whereas places where airsoft are legal involve a lot of minors playing. Whether one agrees with that or not, that's the truth of it.
