I suppose UK politics with a more representative voting system would actually be a multi-party system. Last election, Labour and Conservative got 60% of the vote, and neither would be close to a majority on its own. And that's already with some people voting tactically.

So I guess the two are inextricably linked.

Yes. The rules of the game are the rules of the game, or at least until some nutjob tears up the rule book. It's inextricably linked. So, we play by the rules.

In the UK, if a small-c Conservative has no one to vote for, that citizen should ask themselves whether there's someone they really should vote against and cast their vote accordingly, holding their nose if they must. In the last UK election, I didn't get the impressions that either side was particularly dangerous to democracy or order, so maybe an abstention is justified. I think that this upcoming US election is a little different.

Weimar Germany had a proportional system and the responsibility of actively voting against Hitler moved from the citizen to the citizen's representative in the Reichstag. The SPD just couldn't bring themselves to support the KPD and box the Nazi's out. They opted to temporize and accommodate. Then the rule book was torn up, and it all went to hell in a handbasket.

Both electoral systems can exhibit pathologies if the parties responsibly for saying "no", the citizen in a FPTP system, or their representative in a PR system fail in their responsibility.

While it feels complete to see a comment literally "both sides"'ing electoral voting systems in a full Godwin's law sense, the issue isn't whether "both electoral systems" can exhibit pathologies.

( Addressed in a peer comment https://news.ycombinator.com/item?id=41961834 )

The question is which systems have fewer pathologies, less often and with smaller consequences.

Iteratively spiralling open field non party demographics into a non representative two party stand off is not a desirable outcome.

I agree. The pathologies are strange though. At the extreme, one is a vacillating/occasional hegemony (FPTP) and the other is parliamentary paralysis (PR). I'm inclined to PR as a better system, but it has some weird outliers.
