THIS IS THE SOUND OF A DROPPING BOMB...<3 Fucking amazing band! How can you not like these guys? They are punk and punk is not just a genre. It's about freedom of speech and speaking out. It's not about fashion and if you go back to some of the first punk rock bands they all didn't have mohawks and studded belts or jackets. Some of them dressed how they wanted to and didn't conform to society.
Anti-Flag has the punk rock style, rather you like it or not. They are their own band, and sing for whatever they feel though. Genre doesn't define what they sing, or make. It's just the general style and sound.
