Parties with the most votes should get the most seats. As I mentioned, sometimes the opposite happens in FPTP. Representative government of the majority of votes is the ideal of democracy. That rarely happens in FPTP. It's usually a plurality, heavily favouring Liberals who win seats in the East over Conservatives who win more in the West. From this sometimes Liberals are wrongly given majority mandates.
Back to the video of Teneycke stating "what can I do today to help the NDP", again, that bizarre statement comes solely from the oddities of vote splits (a feature of FPTP). Lewis' NDP and Poilievre's conservatives are on opposite ends of the spectrum.
Many who supported Charest, like DeLorey, in the leadership race felt Poilievre was too conservative. And yet his straight forward style did very well, rather than what some limp noodle like Charest would have done. People want honesty, not "strategy".
The idea of needing to be divorced from ideals ("what can I do to help the NDP") and present a more butterball offering to people, due to the flawed system of FPTP, only disenchants people.
