Stubbornness(?) It baffles me, too. Certainly, one could argue that it would be a fruitless endeavour given the state of mind of the individuals, but the participants of such a meeting would have so much in common that you'd expect there might be a deep-seated connection waiting to emerge therein.
If there's one thing I can be certain of, and no doubt this applies to many, loneliness is a terribly crushing thing for a person to endure. If people are warding off loneliness by talking to others of their ilk online, then you'd expect they'd love to ward off loneliness with actual physical beings that can fully relate to their unfortunate and unusual circumstances.
I don't think you have to hug and kiss it out, necessarily. Not if you don't want to, at least. And to all the 'tough' people that say: "I'm used to it", sure. Keep telling yourself that.
I do the *exact* same thing.
On the subject of friends, I've found through experience that the only successful way to make them in abundance is to lie and fake enthusiasm, which I find terribly difficult to do.
Lie about your mood, lie about your interests, lie about your approval of their hobbies – Couple that with forced enthusiasm, and you'll make many friends that will ultimately mean nothing to you. You'll have to be quite convincing, patient and able to keep up a charade for prolonged periods of time.
Does that sound appealing to anyone?
I tried it a few times, but I couldn't do it for long. I've had normal friends, and I hid my hobbies from them Kousaka Kirino style for a prolonged period until I gave up and just shut myself away because I'd been denied my hobbies for too long. I couldn't even play a video-game for a few hours a week, since I was expected to go out drinking every other day.
I've had otaku friends, too – I ended up hating them due to their disgusting meme-spouting awkwardness and various quirks. Otaku also have a tendency to be patronizing: "Have you heard of JoJo's Bizarre Adventure?"
Yes, I read the (available) English scanlations of it way over a decade ago. Thank you for asking.
TL;DR: To make friends, overlook everything bad they do, delude yourself, feign happiness, blindly approve of them.
