You seem to have missed the point here. Have a look at this post by @CantDealwithChristmas and replies by @RedToothBrush and others.

This is from that post:
TBH, my experience of genuine working class culture, having grown up in one, is that working class people tend to be small-c conservative on social issues, and indeed quite 'right' on some social, economic and domestic policy issues.
The original Labour movement reflected this.
It was Blairism which repositioned Labour towards free market liberalism. It then coopted American identity politics due to the influx of younger members in the late 2010s and that is the unholy Labour 'movement' we have now.
It doesn't really reflect the concerns of working classes anywhere in the UK and the middle classes pay lip service to it cos it benefits them career wise.
This is the problem with the left. People who are holding the left to higher standards are doing that because they are left wing in their political inclinations. Many are or have been Labour party members. They don't complain in the same way about the Tories (or 'the right') because they have never agreed with their politics or voted for them. The Tories are just that party that they would never vote for anyway. They don't expect to agree with them so when they have disagreements with their policies, it's just what's expected.
What do those working class Labour voters do now that Labour has become yet another party supporting middle class interests? I agree with your point about Starmer barely being 'the left' (because that is a large part of the problem with them), but they are still portraying themselves as a party of the left, while not representing the interests of traditional left wing voters at all.
Many left wing people here are saying they have no one to vote for. But some traditional Labour voters (not the ones on FWR) are instead turning to the more extremist parties which seem to appeal to some of their concerns. Labour has to take some of the blame for this because of their refusal to acknowledge the real concerns of traditional Labour voters.
