There are no longer any punks.
There are kids who dress up the way English kids used to dress in the late 70s - like some bizarre ghost-dance religion.
And these imitation punks don't beat anyone up - they just talk about it. They wouldn't want to mess up their retro outfits.
Emo's chord vocabulary, song structures and vocal style comes directly from the postpunk groups like Magazine, The Cure, This Mortal Coil, the Cocteau Twins, Siouxsie And The Banshees, Joy Division, Wire, the Buzzcocks and all the other groups who came out of punk's first wave and then learned to play their instruments.
The influence and pedigree are obvious. The Buzzcocks, in particular, should sue.
You need to get out more. Spend some time in a pit and then talk about not messing up their outfits. Tell Henry Rollins there is no more punk. He will kick your ass so hard you're wearing it for a necklace. Punk permeates most 'hard rock' these days. Overtly punk bands: 'Reagan Youth', 'Angry Samoans', 'DRI', 'Fear' plus many more.
Most of the 'postpunk' bands you list have nothing to do with punk, more like 'New Wave' suckyness. Like I said up thread, lame mumblers that can't play their instruments.
I repeat Emo is an outgrowth of 'Adult Contemporary' not punk.
