Im a loser? Racism? No friends? Help?

I have no friends. I was on omegle (chat room) just before, trying to make some friends. The conversations all went well for the first 10 minutes. I thought the people were great and they thought I was great too. Then when i mention that im arab, all of a sudden they disconnect, or say something like "oh well haha gtg nice talking to you bye". This has happened a lot now and i just don't get it. Im a great person, im nice, im thoughtful, im smart, i respect people the way they respect me, not selfish, caring, always trying to help. But once i say "Im arab", people instantly ignore anything I've just told them, and instead just think 'oh well he must be one of those crazy delusional maniacs that are always on tv'... I don't get it??? Ive never even touched arab ground. Not born there, never lived there, never vacated there, but that shouldn't affect anything should it? Are people always going to be like this? Can i do anything to change this? I don't want to lie by saying im from somewhere else.
