I'd be the first to tell you that the UK has a pretty shoddy emo scene and that I don't think you know what emo is.
It's off shoot of hardcore which was an off shoot of punk. I notice how you only described punk by ethics I think emo is the most musically ethical-elitest genre out right now. If you sell an emo record for 15 dollars you're an arsehole. If you do a show with age limits you're an arsehole. If you charge more than 10 bucks for a show you're an arsehole. If you produce polished grovel you're a god damn arsehole
