People have different value systems - what they value/what they think is ok. The people u r referring to don't understand u. They don't value u and what u have to contribute. Keep searching for your "tribe". Just a suggestion - if you are a very expressive person (dramatic?;) then look into acting in a drama.
I have a best friend that's emo. Me and my friends love her. A lot of people hate her because she dresses all black and people think that's a bad image for someone to be known by and all they know is the stereotype. You know, the troubled teenager that hates the world and is a total nutcase. Try to get people to get to know you and see how much of a joy you are to be around then more people will start to like you. Oh and make sure not to let them think that you are like the stereotype.
It is one of the many social problems in our world. People classify you into groups and judge you even though they don't really know you. Chances are they dislike you for other reasons, but who are they to judge you before they even know you. I'm sure you have some good/unique characteristics that others don't see in you. Try to show they who you really are, but just don't get dragged down by other people's negativity.
"Hate" is a very strong word... I'm pretty darn sure that very few people *hate" you. If anything, they probably view you fairly apathetically! I don't know of anyone who looks at someone and says, "Hmmm, this person looks Emo... I'm going to hate them." They might not be your best friend, but again, they aren't going to hate you. They might not want to talk to you, or share their deepest thoughts and feelings, but that is a VERY different reaction than "hate." People are MUCH more likely to not like someone based on *behavior* rather than appearance... which begs the question of what you are doing that is ostracizing so many other people. Also, while other people are less likely to negatively judge someone who looks Emo, I've noticed that Emo kids are much more likely to judge THEM. The non-Emo kids are judged because they don't understand your emotions, or because they appear to be the "normies"; Emo kids usually pride themselves on being different, so anything that is not part of your Emo-culture is judged. If it truly bothers you that you are so "hated," you might want to check your own reactions to other people. And please don't get mad at me, or say that I don't understand, or suggest that I hate you as well. This advice is intended to be helpful; you asked a question and I gave a sincere answer. I hope it helps you sort things out. Good luck <3
I can't beat my friend Jules' answer. But in a second possibility, they may just be one-sided. They don't know "different" and whatever they don't know, they fear. Whatever they fear, they hide and cover up with laughter. When they laugh at you, they're really just being insecure. Don't worry about it. Now this is the second possibility, standing beside Jules' suggestion. Best wishes.
