I've tried that but they think that paintball is made up of people that don't know what to do with their money and play too many violent video games. I have a unique set of parents -.- and then when i tell them that the paintball community is filled with great people and its not about shooting, its about having fun with your friends doing something you love. My parents say that its still shooting, and it could lead to serious injuries.
Had this problem, my dad is very anti-gun. He also isn't thrilled over the fact that you shoot people. Its important with parents not to try to disprove their point, but to bring up another point that somewhat nullifies their point. When I started in paintball, with a mech in the woods, he hated it. After I saved my money and got a decent gun and hopper,he was still opposed to it, grumbling I was wasting my money. I decided to show him he was wrong. I began to very deliberately disassemble and clean things when he was around, making him see it taught skills with tools. When I shot in the backyard, I wore a mask, and hosed the fence down after I was done, being responsible. Furthermore, I started playing at an airball field more,and told him I wad trying to get on a team. That was what did it. It no longer was a waste of time, it was working together. Many of these things may work on your parents. Overall, don't piss them off about it. Angry parents don't listen
