First past the post is good for the right

First past the post protects egregious right-wing views because people vote tactically to exclude the left. If people can vote for whomever they like (under pr) then even right-wing views will be excluded because people can both reject the left and the right at the same time. Because under fptp voters must choose the least bad of two bad options this enables the right to do relatively well. Pr would make it much more difficult for right-wing views to be tolerated and get recognition because people would have the ability to exclude them. Fptp is good for the right but not for libertarians. Libertarians are not right wing.
