I'd encourage you to be active for everything! The best thing we can do is support each other in whatever movements, demonstrations, and actions to reduce government and its violence on peaceful people that we can. If each only partakes in his own personal interest areas it'll take a lot longer to accomplish anything. But by joining together to fight causes we can accomplish a lot more.
I'm active in police accountability, Bitcoin activism, free software (though not so much strictly in NH), cannabis protests, and whatever else I can find time to partake in. A lot of it is just showing up to events to support others whom have a particular interest in a given area that are fighting for some particular freedom.
