My advice is people should never try to be an “angry nerd” in anything. Games, anime, movies, music, sports. Maybe even cut the “nerd” out. It has a connotation historically for a reason. You’re probably waaaay too interested in just that one thing and have trouble talking with other humans about other stuff. Think of yourself as a “fan” or “enthusiast” instead, but don’t define yourself on any one hobby. For example, a decade ago I was a HUGE angry metal nerd.
I think it comes from a point of personal insecurity and loneliness, at least for me. I had terrible social anxiety, not a ton of friends, no girlfriends. I got off on getting online and yelling at people anonymously on the differences between technical death metal and progressive death metal, yadda yadda. God, I’m embarrased to even say that out loud. I found a point where I realized I was SUPER unhappy with just, everything, and stopped posting online.
I started to actually listen to the music “I hated” and ended up liking it. I found more friends, started to go on dates, found myself actually enjoying myself at parties and social events. Started meditating more, working out almost 5 times a week. Realized that just being positive and nice to anyone, anywhere rubs off on yourself ten times over. Your go-to de-facto mode should be “smile, be nice, positive, and understanding”. Put yourself in the other person’s shoes. Think about morality, and how to improve not only yourself, but your community, and everyone you touch. Be a positive force in the world. I don’t know many “angry nerds” that identify with this, but I sure know a lot of cool people who are interested in different things that are.
Moral is, if you find yourself identifying as a “gamer nerd” I’d highly suggest logging off the computer for a week. Read a book. Ride a bike. Train for a 5k. Try out meditating. Pick up a new hobby. Play an instrument. Learn to draw or paint. Do something constructive, creative, or active. Then, when you come back to gaming, you won’t be “angry”, or a “nerd”. You’ll probably enjoy it twice as much.
Tl;dr, anyone that identifies too strongly with any one weird hobby is probably coping with their own insecurities and it’s healthy to deal with them head on and diversify to different hobbies and interests to prevent becoming an “angry nerd”.
