First past the post is a communist system

There is a strong similarity between the first-past-the-post voting system and communism. If we assume that the established centre-left party (Labour) is not libertarian then only the centre-right party offers an option for people who like economic freedom. If the Tories are the only option for people who do not like state control then this is like one-party rule for libertarians. And one-party rule is the same as communism. If there is no democracy (as there is not with fptp) then we are living in a communist system even if the party concerned claims to be liberal. If we have no choice but to vote for the Tories then we have no choice and it is communism.
