The term "Emo" is used as counterculture; it is an abbreviation of the word "emotional". Emo it's defining not only an attitude, but also a fashion that are coming from emocore (emo music). Emocore is a combination between hardcore and punk music which was very
popular in Washington DC in the late 80's. The emo culture continued to develop between '90 and '00, reaching the height of its popularity today. Emo is also a
popular type of fashion now a days.
The
society thinks emos are failures; they are not strong enough to hide their emotions.
You
don't have to be emo to listen to punk/hardcore/post hardcore music.
Also having black hair (natural or dyed) can't label you as an emo (unless you want to). Emo is used as an insult these days to label
people with high emotions and/or people who wears black clothes.
Emo is not as bad as the
society sees them. Why would people discriminate or judge emos when they have done nothing wrong to the
society but all they have done is having their hair painted/naturally black, listening to
rock/punk/hardcore music, or wearing black clothes.
People shouldn't be judging anyone just because of what they do or just because of the music they listen to. Everyone has different tastes and no one should be discriminating others just because of those reasons.
