Yeah its harsh. But it all depends on perspective. Your definition of Emo.
For instance, you said you see them as sensitive, dark, likeable people. From that, someone who is sensitive and dark but isn't very likeable isn't Emo.
Hell, from that, everyone who is likeable is a little emo according to you
Dark/gothic stuff isn't Emo only either. There are like, 20876895 other scenes with their mits on that stuff.
As far as I'm concerned, emo is restricted to one thing and one thing only: Self harm.
Where Emo's get their bad rep is from people who start innocently like you, who see Emos as cool people, or how you put it, sensitive, dark likeable people, but then go onto start cutting themselves simply to fit into the Emo clique.
I do agree with you though. The things said here really don't do anything to help the concept, as I said in my earlier post, I deeply regret my old posts here.
About Evanscene, haven't heard much of them. I've mostly associated Emo music with stuff like MCR
