As someone new to the sport, I can see why younger people would be put off by certain things Ive come across so far. I deal with school age children with work, have school age children myself, am a beaver leader, and used to play Airsoft into my late 30's. I can definitely say that not all kids are playing video games all day every day, Id say that's more a reflection on the parenting than kids anyways, but that's another discussion.
Attitudes - very detached. Inclusivity is what we need, and that thread starting pic is a good example of the 'harmless fun' attitude prevalent. Doesn't bother me in the least and I get it, but society has moved on from that. People probably don't like the perception of shooting animals for sport either (sure sure, pest control etc).
Guns- many of the airguns are just fugly. Weird bullpups, bulbous bottles, thumb holes. It's got to put people off. I'm after classic lines or something tactical, looking like a rifle should. Tastes/requirements change as we get to know the sport so I'm not dismissing they may have their place.
Activity - some of the disciplines are just boring with little appeal. Benchrest? That's a hard sell for someone fit and able. I kind of enjoy the simple version I do for the AGF comp, but not exactly exciting. PRS shooting, that looks awesome and I wish there were more than one place in the country to try that, for eg.
Recruiting - airsoft would be a great source. I was so pleasantly surprised to see so many young people out playing IRL (in real life). They love spending money, upgrades, multiple rifles, pistols etc. I think it's a natural progression and a complimentary sport.
Now that Ive offended half the forum, remember, we are not our opinions!
