When government takes actions we abhor, like invading Afghanistan or torturing prisoners, we don't have to participate. Contrary to popular opinion, taxes are voluntary. People aren't imprisoned for honestly refusing to pay taxes.
While we're at it, we should withdraw support from the network of multinational corporations who exhibit too much influence upon our government. We don't have to buy their products nor work at their jobs. We know how to raise our own food and care for each other.
