I don't think it's like/dislike; they don't know you so they can't really have an opinion of you other than what they see which is different than they are expecting so they might be a little "afraid". I would try to talk more and offer help rather than wait to be invited.

It sounds like communicating might be a bit of an effort for you? One doesn't usually "try" to smile, one does when one is feeling good and interested in what's going on around them. I would try asking questions about others, it's hard to "ignore" a question. You say "I can't even talk to the one person here I share some interests with, he thinks I'm strange too," how do you know that? Personal perceptions can be weird things; we can think all sorts of things that the other person has no clue about/isn't thinking. I would do some checking of your perceptions, ask the guy you think you have similar interests to a few "hard" questions to see how he perceives you according to him instead of just your own idea.

I was very shy and didn't speak much and know I was thought aloof which always amazed me since I was usually frightened and feeling left out instead. It's not the other person's job to include us; they're too busy getting themselves included and putting themselves out there where others can "see" them. If we do things differently than others are accustomed, we have made it a bit harder on ourselves to help other people see and communicate with us; if you're not a man and you wear men's clothing, other people don't know how to respond to that; you have to help them, if that's what you want.
