There may be variance from place to place, but most national parks are extremely restrictive on when people can come and what they can do, and at least in my state, most Bureau land is off limits to the general public for most of the year.
While I don't care for the song, NPR calling media enjoyed by the lower classes "racist" isn't exactly a new thing, and it rings less true every time they do it. The song, at its core, is a generic "We're tougher than you" machismo piece which is a perfectly normal thing that can be found in most genres. Someone from Tennessee writes a song about how country people are tougher, then someone from Compton writes a song about how city people are tougher. It's just dick waving and it's normal thing everyone does, whether they realize it or not. NPR trying to turn it into a race thing isn't convincing anyone to change their musical taste, it's just fanning the flames of a conflict that pits working-class country people against working-class city people, in which everyone loses except the ones taking advantage for profit.
I don't disagree with this, but it sounds like you're talking less about violent crime in general and more about sexual battery and premeditated assault, which makes up a relatively small proportion of violent crime.
Most violent crime is just regular conflict that escalates into throwing punches, and throwing these people in prison is the quickest way to push them away from lawfulness and down the path of crime. Prison is just networking for criminals.
Based entirely on your comment, I would say the issue isn't the concept of ideology, but the fact that the ideologies that matter the most and the ones that spread the fastest aren't the same. After all, the idea that no one should starve is itself an idealogy.
