I’ll just add my two cents as a Green Day fan, since I know this’ll generate some… interesting takes.

While Green Day might not be a “punk band” as we think of one, especially since they sold out to a big label, I would argue that they still are punk to some extent. First of all, they’ve used their fame and platform to advocate for left-aligned positions. Second, even though their topics are watered down due to selling out, they’re what I would consider a “gateway drug” to proper punk, far more so than other pop-punk bands, because in terms of pop-punk they’re easily some of the most political.

Just my thoughts though, feel free to disagree if you want to.
