Let me establish a few things:
1.) Punk was born about 1976/77
2.) The Ramones were not a punk band, they were rock. They said it themselves. Neither were the New York Dolls.
3.) Punk died in 1986. That's when Minor Threat broke up, Bad Brains turned reggae, and every other hardcore punk band either broke up or turned metal.
4.) NOFX has been pop-punk ever since they released "Ribbed", 1990. They were hardcore punk from 1983-1988.
5.) Anti-Flag has never been a punk band, and never will be. Pop-punk sucks.
6.) Neither are the Distillers
7.) Or The Casualties
8.) OR The Buzzcocks (first pop-punk band ever)
