The lines aren't blurry. The people who call the bands you listed emo can call any band emo or any other genre- that doesn't mean they're correct. There's an entire culture of people associated with emo and screamo with values that started with 80s hardcore. The bands you listed have nothing to do with that culture. They don't share those values. Those values, along with the music, are what define a band as emo, screamo, hardcore, punk, whatever. It's not about being condescending or elitist, it's about filtering out the listeners who share those values from those who don't. How would you feel if you invested your life into a culture that has no "real world value" and then people who thought you sounded and looked "cool" copped your style and assimilated it to turn a profit? To add insult to injury, what if that culture became the subject of constant parody based completely on people's ignorant and inaccurate perceptions and depictions? How would you feel then?
