I grew up around quite a few as they are pretty common in the Middle West especially middle and low income areas. Aggressively inclusive is a pretty good description of the subculture's values. There's some bullshit like anti science and anti education, but it comes from the elitism and exclusivity of those institutions which is a problem in public outreach and inclusiveness in academia. Most of the juggalos I've met just want to do drugs, listen to horrorcore rap, and watch wrestling, but I've also met some that can't stand any of those things but just celebrate the stuff they do like instead of denigrating other people and their aesthetics.
