It's easier to teach kids about gun safety than teenagers. True story.
Also, bad rep my ass. Kids have been playing airsoft in manitoba league for like 3 years now, and there's a LOT of them. Not only are they GOOD for the community since they bring up properly trained airsofters, but they're actually really fun to play with too. Consider the shape of the average airsofter on your own fields, how many of those people would you HAVE to run a mile around to flank because they're so active? lol
It's not the kids that are the problem, it's ignorant people who don't want to teach them about airsoft! If they didn't have a supervised and (strictly) controlled environment in which to play airsoft, I'm sure they'd be playing in the street with no eye protection.
