This has been brought up before, but I agree with Phylodog on this: if you're not doing your civic duty and participating in the electoral process, you may as well be a child in the eyes of the law (NOT dragging Phylodog into that last phrase). If you don't think you have a responsibility to change your government if you don't think it's working for you, you're thinking and acting like someone who feels no sense of responsibility: that's not "citizenship." If you want to ***** about the government, but you won't act to change the way it's run, and if you insist you're a nominal adult, perhaps you should search for another country with a government to your liking.
You sound angry. Anger leads to hate and all that... Here is a video for you.
