*It is worth nothing that there is actually a Christian "sound" in hardcore that is slightly different from non-Christian bands, so there is a musical differentiation, not just lyrical content. It's more moshy and has a far higher percentage of songs consisting of breakdowns.
**This includes about six bands total, none of which are active today.
mostly white people music, no? Given the demographics, I would say most of the above probably lean GOP.
So by this logic, the coffee shop across the street from me which has a well over 90% white clientele has a mostly Republican customer base. And the people at the hundreds of shows I've been to which includes anti-Iraq War activism fundraisers and recently a fundraisers against the Minnesota gay marriage ban and Voter ID amendments are mostly Republicans as well. This is what a gathering of Republicans looks like! Oh and as this photo is almost all white people it's obviously that most people in it are Republicans:
Demographic simplification fail.
I think you are the one vastly simplifying things here. You sound like Bandit transposing his own deeply-held views on his immediate environment and concluding that Occupy is a slumbering political force in Kentucky. Just because a couple hundred mostly white students or hipsters show up for a rally like that says little overall about the voting patterns of whites generally, even in MN.
This is a cute thread topic (albeit one whose author was immediate apparent from the title), but don't kid yourself into believing that demographics like race and income aren't a trillion times better an indicator of voting habits than what type of 'core' music someone's into.
