Most people are not communists so pr is better

There is a difference between democracy and communism and so we can deduce that it is better to have as much democracy as possible... which means pr is preferable to fptp. If the type of democracy being used makes no difference then democracy itself makes no difference and the voters effectively choose communism each time. If people think that voters will always choose communism then the voters are not liberal and do not restrain the government and we might as well cancel all future elections. If elections are pertinent then we can say that the voters are liberal and not communist and so we want the voters to have full democracy (if we too are a liberal). Unless all democracy leads to communism (or liberalism is bad) it is better to have pr than fptp because voters are liberal. Only if liberalism is bad or if all elections (whether fptp or pr) lead to communism is it possible to say that fptp is a good idea. Only if all elections are (result in) communism and are redundant would it be possible to say that pr is not preferable to fptp... if elections matter then pr is preferable (and liberal). If elections do not matter (always result in communism) then there would be no reason to switch from fptp to pr... in all other cases (when democracy matters... and does not inevitably lead to communism) it is better to have pr. If it is not better to have more democracy then democracy is useless and people always vote for communism. If people vote for something other than communism then pr is preferable. If democracy is not always communism (people are sometimes liberal) then we can say that pr is more liberal and therefore preferable. People do not always vote for communism... so pr is preferable. We know from experience that given democracy people do not choose to have communism... communism is unpopular and so we can say that more democracy (pr) is always preferable. Only if everyone (more than half) is a communist would it make no difference to switch to pr... but it would do no harm either.
