Fptp is a problem if we do not want socialism

First past the post is problematic because it assumes everyone is sympathetic to the government... if we are agreed that the government has a valid purpose then to be asked to choose from only two possible candidates is not so bad as we assume we have been given a choice of the best available candidates. If we can choose from between the best from each party then we will not suffer too badly... so the thinking goes. But if we are a cynic of the government as a whole then fptp is problematic because the assumption that we want a good socialist no longer holds. Fptp is fine if we accept that socialism of one kind or another is required... then we can choose the best of the two available. But if we do not want any form of socialism then fptp gives us no choice and is bad. Pr is preferable if it possible that socialism is bad. Fptp is fine if we always want socialism.
