Personally I find it stupid to align emo with suicide.
You'll find alot more deaths concerning other ''stereotypes'' who hang or consider other means of ending their life.
I find myself surrounded by alot of emo people, and most are extremely happy with their lives.
I myself have been called emo and I have no wish to end my on life. Far from it infact.
It's all about the person, not the clothes they wear or the music they listen too.
Its harsh to judge someone on what they wear and what they listen to, just because of a few. They may find you also annoying and irratating because of your long hair and rock music, or your trackies and gold rings.
It's all about the personality and then you can judge that person to be nice or not.
