Rational people accept that pr is preferable

The opposite of democracy is communism... when there is no means for the people to reject government (when there is no democracy) then communism or something like it will result. All forms of tyranny are similar to communism. Great harm cannot be done by a single person alone. It requires a group which is not accountable to its subjects to cause tyranny. Without democracy there is communism and tyranny so it is better to have pr than fptp. There is always a state (anarchy is impossible because there would be no property rights) so the pertinent question is which type of democracy is the best. (Is it better to be ruled by two parties or many?) It is inconsistent for a liberal to support fptp because it is less democratic than pr which means advocates of fptp are statists. Democracy is bad for the state and good for the people so people who reject pr are defending the state. All anti-state people (including anarchists) prefer more democracy to less because more democracy means less (unwelcome) state. People who defend fptp are guilty of defending the state... or perhaps they do not realise that democracy is the only means by which society can be organised. If someone is waiting for the return of the messiah it might be consistent for them to reject pr in the hope that something better will come along. But there is nothing better than democracy so there is no reason to reject pr. There is no rational reason to reject pr.
