Is built by people, designed by people, contributed to by people, and most importantly exists in stateless societies. When a community has a common need and enough spare time to address that need, infrastructure happens. A government not only is not needed for this, but objectively halts or stalls progress for a variety of selfish goals of the individual politicians, as humans cannot be politicians, just parasites.
Incorrect, assuming said third party is not advocating for genocide.
Democrats are advocating for genocide and explicitly state they will help so genocide if you vote for them. If you vote for them you are complicit in genocide.
Republicans are advocating for genocide and explicitly state they will help so genocide if you vote for them. If you vote for them you are complicit in genocide.
Therefore the third party that is not advocating for genocide is the only way to not be complicit, besides not paying your taxes and kicking the draft officer in the sick like all military members deserve.
