True, but if politics are deeply baked into a genre it is part of the genre. Post 9/11 country is pretty right wing, I accept that, if I’m listening to it I accept I’ll get right wing content unless I seek out left wing country. Similarly if I’m listening to Appalachian folk music of the early-mid 20th Century It’s gonna be communist as all hell. It was a genre defined in part by its association with a location and time and the politics within it, namely being extremely pro unionization.

Punk is similar but it broke containment. Punk is deeply tied to anarchism and antifascism. There are punk musicians, including famous and foundational ones who aren’t, like the Sex Pistols, but the by the time the genre had solidified anarchism ran in its veins. If I go to a random punk show I expect far left, anti bigotry, anti authoritarian themes in the same way I expect themes of romance and desire at a pop show. It isn’t necessary to keep and it certainly doesn’t need to be in every song, but it’s expected and it’s inversion will be something notable.

It’s called cognitive dissonance, when a person holds two conflicting ideas or beliefs. It’s stressful to acknowledge the conflict and change beliefs and behaviours, so people instead do mental gymnastics to justify holding both.
