As an Alaskan voter, ranked choice is the only reason we have a female, Native American, Democrat congressional representative instead of Sarah Palin filling Don Young’s deep red legacy.

Peltola would have won under FPTP, too; RCV didn't change the outcome. The real issue is that there were two Republicans on the same ballot vs one Democrat, splitting the vote with each other.

RCV is equitable and works, but not in the way progressives hope. It allows for the most centrist candidate to be chosen that appeals to the most possible people.

No, it suffers from the center-squeeze effect and is biased against the candidates that appeal to the most possible people. In Alaska's special election, for instance, Begich was preferred over both other candidates by a majority of voters, but RCV incorrectly eliminated him first. This flaw gave an unfair advantage to progressives in that election, which you may like, but it could just as easily give an unfair advantage to conservatives in a future election, which you wouldn't. (If there are two Democrats and one Republicans the ballot, for instance.)

In my opinion, for single-winner elections, we need better voting systems that do always elect the candidate who appeals to the most possible people, which will allow third parties and independents to become viable, which will open people's minds beyond the two-party false dichotomy.

A two party system just becomes a battle of political extremes. And like it or not, being progressive is far left for a reason, especially in America. And I consider myself fairly progressive leaning.

Yes, and RCV perpetuates that polarization because of the center-squeeze effect.
