@Pizzabeak First of all, if this comes across as "attacking" you, it isn't. If I understand correctly, you basically asked why you wind up in situations where you're socially humiliated. I'm providing my opinion on possible reasons.
Perhaps you see it differently, but I don't think there were attacks on you and don't believe most people would think so, either. At least in the cases I've seen, both ones that I have and have not been involved in, 1. nobody even addressed you directly and 2. your comments (i.e. "you suck") seemed to come out of nowhere.
You seem to be assuming that your perception is objective reality. Like, after you feel attacked or belittled by somebody, you assume that they were trying to attack or belittle you. Or that they were talking to you at all, which doesn't seem to be the case from what I've seen. You also said to moody,

I don't ever recalling offending you
But it's not about whether or not you remember saying something that you'd consider offensive to moody, or whether you saw moody visible express offense (I get the impression that he/she is fairly passive, anyways). All he/she is saying is that (okay, imma just go with he, whatever) he found some of the things you said to be rude, which isn't something you would know without him telling you so.
You also seem to think that things have to do with you when they don't. Like, your signature? How do you know that people are acting "differently" than you or than the majority because they want to assert superiority over you? What if it has nothing to do with you? I'm not just bringing this up out of the void, though; it seems like the sentiment in your signature was precisely why you decided I was trying to put on airs over you (my thread on the #3). I was not.
Having different tastes or interests than the majority isn't always an attempt to assert superiority over other people. Being different than you isn't always an attempt to threaten you.
Tangentially, I think it's worth pointing out that you said you wanted to listen to and discuss people's interesting thoughts, but also disdained "excessive intellectualism" that you consider impractical. So, what, if somebody is interesting in something that doesn't appeal to you, that's not practical enough for you, it's too overly intellectual? It's an attempt to make you feel dumb? Again, other people are different from you and might be legitimately interested in things you're not. They're not trying to start a fight with you, and it's kind of self-centered to think it's all about you like that.
One distinction to make between your behavior and that of the people you're "retaliating" against. You're assuming things are targeted at you, whereas the things you say are undeniably targeted at people i.e. typing @ and a user's name before directly insulting them.). People get upset and rebut your insults, and you have no response, which makes you feel more shown up.
My suggested solution is that you try to keep things in perspective. Don't assume people are like you, don't assume people are doing things with you in mind. Actually, assumptions in general are something to be wary of. It's like when a friend doesn't text you back and you assume they must be mad at you, but it turns out they were just busy. It can be hard to remember that the latter is more likely true, but it's a lot better for your emotional health if you do so.
