Honestly, I feel bad for you. I'm only 11 years old, but I feel you! I've never insulted any adults for gaming; I actually think it's pretty cool. I always imagine myself gaming as an adult and being really good at video games. I know that when I'm an adult, I'll definitely still be gaming. Keep it up man, don't let anyone stop you. My friend's dad plays Destiny, and I think it's awesome. I even joined his clan! There's nothing bad about being an adult gamer. I think all adults should play video games. Then they'll actually understand what the kids say when they're talking about a video game lol. (That wasn't meant to be mean, it was just a joke.) Keep gaming!
