Yeah you can say that to suit your narrative, but it’s complete BS. In fact Corbyn had significantly more votes in 2017 and 2019 than Starmer in 2024.

Which governments did Labour form at the time, again?

The left has to convince voters, not follow them, wtf

Electoral success and convincing people are not mutually exclusive options; the former is an immensely powerful tool for the latter. Unless your plan is "Hand the gun over to the fascists, put it to your head, and hope that when they pull the trigger it will inspire the masses to spontaneously learn the words to the Internationale in their hearts and rise up against fascism", it involves some amount of concessions to the majority of voters.

But sure, run on gay marriage in 1940 until you win, I'm sure the Black folk who are being lynched won't mind waiting another few decades, nor will the unions seeking better conditions, nor the folks trying to stop social security from being repealed etc etc etc etc.
