If you vote, you consent to everything the state does. If you don't, you can't complain!
Since outright slavery has been discredited, "democracy" is the only remaining rationale for state compulsion that most people will accept. Democracy has proved only that the best way to gain power over people is to assure the people that they are ruling themselves. Once they believe that, they make wonderfully submissive slaves. —Joseph Sobran
