I dont know what the big deal is about here. It's just a guy ranting about underage airsoft, doesn't that remind anyone of ASC?
Not wanting to be a stick-in-the-mud, however, I have offered to supervise airsoft battles between my son and his friends in a nearby sandpit or another suitably isolated location. That way I can make sure the guns are being used safely, safety glasses are being worn properly, and fights are fair.
This is what it's about. The guy isn't against airsoft, he's against irresponsible use of airsoft, he might be less informed but still.
