Fill it out or don’t, but please, quit WHINING about it! Is it really that much to ask that once every ten years you answer a few simple questions truthfully and accurately and to the best of your ability? Is it really necessary to go out of your way to make things difficult for the people whose job it is to tabulate your census form by putting in fake races, ages, people, incomes or whatever? What thrill do you get out of it? Some people are complaining that there are too many questions. You get asked these questions once a decade, so averaged out you’re answering questions at the rate of one or two a year.
Don’t want representation in Congress? Don’t want federal money for your schools? Don’t want to do your Constitutional duty as an American? Fine. Don’t. More representation and more money for me. But if you don’t want to answer the census then at least have the good grace to shut up about it.
