If you want the government people to leave you alone you have to stop obeying them. This is a tough thing to do, and it's silly to just jump in the deep end of noncooperation, so saying NO to the census people is a good starter disobedience. Have your video camera or audio recorder handy, and don't be rude or mean. These people are mostly just folks looking for some work; they aren't the government's aggressors. They probably don't realize the money for their checks comes from coercion and fraud.
