I think the problem will arise when paintball pro-shops start carrying Chinese airsoft. Large influx of probably younger people, with bad guns. At that point, the question will become what makes an airsofter? What differentiates us from them? I'm sure some people will say they skirmish while we milsim... What happens when the kids want to milsim too?
If airsoft is sold at Splatters and Flag Raiders and so on, what's stopping them from saying we can only use field-purchased BBs? Airsoft becomes the next paintball. Nutjobs like us who play bushball, and the next generation of airsofters, playing tournaments with corporate sponsorship.
