I'm pondering a non-profit, no gambling, mouthpiece and pads fight club for headbangers only. Maybe this would only take the shape of an annual convention, but it would serve to:
1) Gather Hessians
2) Draw attention to metal society
3) Information videos with propaganda
4) Get people healthy and motivated
5) Donations, band, music and arts promotions
6) Tours, lectures and conventions
7) Hessian warrior school and security company
eight) Fight arena combined with concert events
9) Political Action Committee
10) Hessian cultural centers and communities
The biggest drawback (#7) is probably local laws and liability. Nevertheless, boxing and karate fighting schools legally operate, so there is a way.
