It's understandable that you feel such a way towards random "Hate" posts and such, don't let such a small thing like that get to you though..it's the internet, no one is liked by everyone. Of course you also have to take into consideration..you sort of bring people to call you emo simply because you listen to that particular genre of music whether you decide to call it that or not, anyone who isn't emo is probably going to show some anger towards that. Be yourself if you aren't already, your sort of ..falling into a generic mold that so many people tend to fall into. The whole, "Don't label me" labels are labels and they exist, why care what others think or label you as? I won't even begin to say what I have to say about your music and what so many others do, granted people can often say things about what I listen to; Black Metal, Grind, all of that. However, emo is just so openly hated and easy to target..you can't blame people for doing it. Emo is generally just a modern "Mod" if your familiar with the "Mods" of the 80's, (Mods and the Rockers.).
Express yourself in a new way, be who you really are and don't conform, at least in other genres it may look similar but surely it isn't conforming, emo is just a widespread thing that all of the "Teenyboppers" are into.
I don't mean for this post to be hurtful, hateful, all of that as much as constructive, therefore I must express something that needs to become a global realization.
Emo sucks.
