ACh, after reading this thread and your previous one, I had the following impressions:
1. You seem a little full of yourself, in the sense of being smug about your intelligence. I fell into the same trap long ago, although I am much better now. Such a sense of superiority may come from low self esteem, and in my case it did. My advice: most people, including the cowy masses at your school, should appreciate your intelligence if you're nice and not pushy about it; but the inverse is also pretty much true, with some differences (e.g. some capable people might cut an obviously capable though pushy person some slack). Some of your classmates have probably picked up on your attitude towards them, unless you've hid it extremely well.
2. You seem to be too eager to impress others with your intelligence. Your writing style comes off as a bit flighty or nervous, but I think this is mostly because your word, phrasing and sentence-structure choices are designed with the total message in mind: you want us to know that you are quirky, have a decent vocabulary, etc. My advice: relax.
You don't have to work to make people like you, and trying too hard to appear intelligent generally isn't the right way if you
do decide to work at it. You also don't have to worry about convincing anyone here that you're smart.
3. People are not worthless or beneath you simply because they are less intelligent. Intelligence has a flexible definition in the first place, as you must know. You have surely enjoyed some products of people who would have scored well below you on intelligence tests; this might include books, movies, food, and a thousand other fruits of human labor. A good number of those people would actually perform better than you on at least some real-world tasks. Some of them would also score higher than you on one test or another; that doesn't make you a lesser being either.
4. If you are really having trouble coping with lesser ability in others, or different viewpoints (which often include some sort of prejudice or another), I suggest changing so that you are a less irritable person. It sounds to me like simply making a conscious choice to adopt a different attitude for a while might work fine; other options might include therapy to address some of these issues. You'll have a happier life if you can appreciate the good in others, instead of focusing on what you perceive to be bad; you might even notice a lot of good that way that you would have missed otherwise.
ETA: I think no5no5's dogs-and-silverware comment is a good one. I would add that if you've ever liked a dog, or any other being that's less smart than you, you can eventually see your way clear to liking some people who are less smart than you.
