Having and believing in a right to representation in your state or community does not equate to liberalism as you claim.
The same ridiculous argument that you make in regards to taking personal responsibility could be applied to any area of life including drug use, sexuality, foul language, violent behavior, etc
In your world we would have no right to representation on any of these issues and the only rights we would have would be in regards to our own home. This is a version of anarchy.
We today make laws dictating that people clothe themselves in public but by your logic why should we be allowed to tell others whether to clothe themselves? Just take responsibility for your own actions only is your philosophy and have no say on public life is regulated.
Why should we be able to have age of consent laws in states? By your logic we should only have a say in regards to our own children.
Why have laws prohibiting hard drugs? By your logic we should tell our children to stay away from it but have no right at all in making laws prohibiting it.
You are a libertarian anarchist who seeks to take away the Peoples right to representation on issues.
Because everyone who might reasonably set a different bar of government interference, immediately becomes a LIBERTARIAN ANARCHIST DICTATOR HIPPY NAZI to you.
Cut it out.
