*sucks in air, and tries to place this in context* I.. am not actually sure where to go with the original topic, but I suggest that you neither use the word elitist nor veteran when describing yourself. Elitism requires you to form an elite, i.e. a group of like thinking people who happen to have knowledge, skill, wealth or power that props them up above the masses. And knowledge something exists is not necessarily enough to be considered above the masses, as a wiki check and a day could see me on equal footing on any topic related to your knowledge base.
Nor, mind you, would I suggest calling yourself a veteran, as to be a veteran at something you have to be able to do something with the acquired knowledge or skills. What is it you have done with what you know, Sung-Hwan? What accolades can be spun from your knowledge of "gaming and its sub mediums, several hundreds worth of anime seen, ongoing activity in visual novels, overall knowledge, and experience as a partial writer for specific groups." Do you ply this as a trade? Do you teach those whom are to poor or to tired to spend as much time and resources as you anime?
Here's the issue I have with this post, you either understand what you have is worthless and you have chosen to build a shrine to it, or you are literally, genuinely baffled by social norms in which case you deserve neither title; you are an anti-social.
Now that we've properly defined you, allow us to reevaluate your question; Is it possible for an anti-social to fit in with the masses?
The short answer is very easy: by definition no. The long answer is where we get into the bread and butter of this post. Not if you don't want to, and find those who have different lives, pleasures, hobbies and knowledge as beneath you. The trick to handling the masses is being open to dealing with conversations that don't pertain to what you find fun, then if you have an opening and are friendly about it you can suggest a conversation that allows you to talk about things you do find fun. Try not to do this at length however, as this will cause your audience to become bored.
In debating things with random people, I recommend applying detailed resources on verifiable proof on the subject to only as much as is necessary. Showing off a youtube video is polite, delivering a dissertation on why you feel you are right is a bit much. I know how much you want to show everyone what you are passionate about, but changing someone's opinion is like tending a garden. Seed the idea, and let the land do the growing for you. If you get a chance to speak with them again, ask them if they've checked out what you've shown then but do not implore the conversation.
Most importantly, try everything. You are still very young and getting out among others of your age or better will show you more of the world and expand on your interests. You will never know what you like until you try it, surrounded with those whom have experience in that activity (who I am sure feels about their own hobbies and interests the same as you do in yours).
One day, maybe you will find the right combination of interests to profit from them, maybe as a reviewer, or a writer on events in the field, but you will not manage this without the right attitude (or more hard work then I would wish on anyone...). Til then, enjoy your day, and think on this. [footnote]The wood that makes up you is still subtle and full, consider what kind of tool you wish to be and whittle yourself into that mold. Do you wish to be a mallet, and see every obstacle and interference as a nail to be hammered at until you break or it does?[/footnote]
