Hey weebo, I think everyone just made it clear you shouldn't bring airsoft guns out in public.
Just because you wanna be pigheaded about bringing to a convention once a year, you want to risk fucking things up for the rest of us who are in the sport all year round;
Just because there are other retards already doing it doesn't mean you should contribute to the problem.
If you really want to bring something bring a prop made from a NERF gun or at least a clear airsoft from CT/walmart (and leave it clear so it can be easily identified as a toy). Like people already explained, there's people getting arrested by overzealous cops for way less than this: don't be stupid.
