Err… as it says on the page:

- Arrow's theorem does not apply to first past the post

- Arrow's theorem does not apply to proportional representation

- Arrow's theorem only applies to ranked voting systems.

Arrow himself said about US elections (FPTP), "The first thing that I'd certainly do is go to a system where people ranked all the candidates."

So yeah… I’m still maintaining FPTP is less fair, as the evidence you supplied is not applicable.
