In the past, I helped organize/manage a folk music festival which donated all profits to the local food bank. I have also played at several charity events (free of charge - not even compensated for milage, etc.)
Since I moved back home to northern Wisconsin, I have donated time to the local food bank, cooked for free community meals, helped tutor children in reading, and provided tech support (free) to churches (even though I am an agnostic) and retirement communities. I help out with Scouting - even tough I strongly disagree with the prejudice of the BSA ever since the Mormon church essentially bought it out (the BSA actively discriminates against gays and athiests). While I think the BSA has been corrupted, they still offer some good - especially in my small town where the political/religeous agenda is basically ignored.
I don't just vote (the least you can do), I am politically active and write letters to my congresscritters, even actively protest (non-violently, but not always lawfully) when the situation calls for it.
Everyone knows the old saying that "The World is What We Make of It", but few people truly take that to heart. Not just the world, but our Counties, States, and Communities are what WE, as individuals, make of it.
Democracy fails when the people can't be bothered to care - and are too caught up in their own little problems to make a stand against the bigger problems that actually cause the little problems.
I don't care if you agree with me on any particular issue. As long as you have given it some real thought, and stand up for what you believe, you will have my respect.
