I'm nearing 30 and yet I understand your issue. In my experience young players can be more fun, driven and respectful, even in raids than older players, such as myself. Human nature is horrible and because "its the internet", many don't think it matters what they say or do and how it impacts others. I've met the whole spectrum in Destiny and I'll take a good mannered "squeaker" over an older person with a disgusting personality. I hope that you find other like minded people so you can enjoy Destiny the way it was intended.
