Democracy enables people to reject the left

The purpose of democracy is to hold the government to account and to prevent it being too (economically) interventionist. In this respect we assume that all politicians are aspirant interventionists and socialists even if they claim otherwise. If we do not fear the government then there would be no reason to have democracy at all. In a democracy we assume all parties are to the left of the voter so the left-right dynamic which is often referred to in a fptp system is not true. There is no right-wing in a democratic system all political parties are to the left of the voter. In a fptp duopoly one of the main parties might claim to be right wing and to offer voters an opportunity to block the left. But this can never be true because all (democratic) political parties are leftist. Since all political parties tend to leftism it is best to have a proportional system whereby voters can choose smaller and smaller parties to represent them. This means that voters (if they want their vote to be meaningful) are not compelled to vote for the least leftist of two leftist parties. They can vote for the least leftist of many leftist parties. Giving voters a choice of more than two political parties means that they are able to reject not only one but many different forms of tyranny and leftism.
