Parents won't let me play airsoft, because they think it's dangerous and will give me an interest in using real guns to shoot people. -_-
You need to bring it up as a sport. You also should get videos of Gameplay too. You need to explain the game, not just say "hey ma I want to play with guns that look real and shoot at people with them". Trust me, just bring it up as a sport, it worked for me. :3
