Can't Hold Leads
First past the post is underrated. It has put us in a pretty good spot. I'm totally fine with parties representing the lunatic fringe remaining irrelevant. Also, I have no clue how anyone bought Trudeau's "2015 will be the last election under first past the post." It was painfully obvious it was a promise he couldn't deliver and he was just trying to syphon some naive dipper votes.
I think people underestimate how FPTP can allow lunatics to gain power and influence. Under FPTP most of the fringe simply join one of the big parties. Sometimes that fringe doesn't gain any traction in the party, but sometimes they can get their people in a leadership position. This threat is even more present when we are in times like we are now where society is getting more polarized and people are moving away from centre, however it can happen with just a leadership race with a split vote among a bunch of moderates. But the more likely way for the fringe to gain influence is to get concessions from their own party (when it is in government). Governments still have to please many factions within their own party to stay in control and it is entirely possible that parties that aren't extremist as a whole have extremists in their ranks. Under a proportional system you may get extremist parties in parliament, but (at least in theory) minority governments would look towards moderate parties to pass laws. The biggest threat in my opinion would be parties holding to firm to the idea that "the other big party" (which isn't extremist) can't get in power, even if it means "we make a deal with the extremists on our side of centre". Sweden had an election a few months ago where a couple fringe parties grew and neither of the traditional coalitions had enough seats for a majority, but one coalition managed to make a deal with a couple of the centrist parties from the other coalition for support. I'd much rather see that than have fringe factions have influence within the government.
