That thing on wikipedia is nothing more than a link redirection problem. 'Gothic' is often used to describe AFI's image (inaccurately or not) and so 'gothic punk' was listed under AFI's related genres (a little inaccurately - horrorpunk would have been a better choice). There's no 'gothic punk' page, so it redirects to the closest thing to gothic punk, which is deathrock. It isn't saying AFI
is deathrock so you can calm down...
(And also... Rozz was cremated. No 'grave rolling' for him I'm afraid. It's kinda sad though because it means there's no hope of him coming back as a zombie
)
