In an unrelated point, I think it's important to point out that I have a very good chance at being prom king this year (as people who make homecoming court can't run for prom court, and I wasn't eligible for homecoming court but will be for prom court)
In a more serious and relevant point:
Part of the reason the TSC community tends to pick fights with you is something you're already aware of; you like to get in people's heads and see what side of the fence they stand on. There's no sugar coating that when you intentionally antagonize people to study them, they are going to feel antagonized. That creates conflict, end of story.
But, likewise, I really don't think anyone in the IRC community directly hates you as a person. Genus might be condescending about your choice of lifestyle, flyby may think you attach too little meaning with sex, I might disagree with you on pretty much every issue on the face of the planet. But, speaking for myself, I don't think you're a worse person for that, I just think you're an outspoken person who likes to argue, and you happen to be in a community contrary to your primary views.
If you're leaving the TSC community because you don't want to be a part of it or because you want to get your life fullfillment elsewhere, have at it. I'll applaud your courage to leave to pursue whatever else you like in life, I can't do the same. I don't compete any more, I hardly chat anymore, and I really don't understand why I still frequent TSC, but I am unable to bring myself to go. I'm really not sure why that is. But if you're leaving the IRC community because you feel that everyone is out to get you, I hope you can change your mind on the issue.
You say that life can't have meaning without a romantic relationship; that may be a true statement for you, but it's very possible that someone else doesn't want a relationship. But even for people that that is true for, sex may not be that important to the relationship, but even detrimental to it. You are telling me that you prize the value of sex and that sex makes your relationships stronger. Does that not make it even harder to lose a relationship when you've added this extra element to it?
My main objection is your caricature of the TSC community as stereotypical nerds. We don't all live in our parents' basements. We don't all play video games non stop. We don't all refuse the social aspect of life. We prize intellectualism, but can you really say that you like dumb people more than smart ones? Just as you act a certain way in IRC that doesn't reflect your real-life person, all the people whom you don't think you fit in with may do the same.
If you still want to leave, have at it. Doing something that's more rewarding to you in life is the right choice (especially if this IRC community isn't rewarding to you at all). But please, please don't stat bomb. There -are- people who still care about the leaderboards. There are people who really care about how they measure up to other people in the world. And deleting your stats (or alternatively fake stat bombing) makes their comparison all the more invalid. If you have good stats, you can leave them up. It's not a prerequisite that you have to stay at TSC to keep your stats up. Those can still be up to make life a little more rewarding for those who find reward in sonic competition.
sorry for the tl;dr, though I'm sure you are used to my tl;dr posts by now.
