A responsible citizen doesn't impose his will and desires on fellow citizens.

this gets really hairy though, doesn't it? Any dedicated reformer is trying to "impose his will and desires on his fellow citizens" even if one defines that as trying improve lives and general well-being. Are those who who fight, for example, for racial equality in racially-divided and racist communities irresponsible citizens? I have trouble with that idea. It kind of sounds similar to the old "If you don't like it then you can get out" mantra, which I think is narrow-minded and counterproductive to progress.

I might even go as far as to say that a responsible citizen has an obligation to try to improve his community and surroundings as he sees fit. Your city doesn't have any sustainable urban gardens and few local grocers? Start an urban garden, educate your peers, and support the local grocers, even if all the Walmart employees and big-business fans in the area don't like it. Does your city have air that's dangerous to breathe because of smog? Fight for stricter emissions laws in your state. Is that imposing will and being irresponsible?
