Wanna become stateless?

i am a citizen of my own country by birth but i didn't ask to be born one of its countrymen (nor that of any other countries), and it is pointless in supporting your country/showing patriotism (patriotism kills... think about the damn wars) just because you were born to be its member. i belong to the world, a citizen of earth, so is every single person out there. is there anything i can do to give up my citizenship and become stateless?
