These systems are ostensibly biased towards moderate candidates, but when there are no moderates as in these days of wildly antagonistic partisanship, the result is disenfranchisement.
Instant runoff is vastly superior in terms of allowing people to express their voting preferences.
But the candidates we have are a reflection of the voting system. That is to say, hyperpartisanship is a feature of FPTP and so our candidates are a reflection of that. A voting system that rewards moderates will bring about more moderate politics.
Biasing towards supposed "moderation" marginalizes a broad range of the citizenry outside the mainstream and breeds cynicism and fury. Even if they cannot command a policy-enacting majority, minority opinions deserve a voice.
People should be allowed to vote for representatives who actually represent them!

People need to stop seeing voting as some kind of identity affirmation.
