Well it's right that Corbyn left Labour a shambles and his actions since really haven't been helping the Party.
I've been quite impressed with Starmer and he's held the Government to account more than Corbyn ever seemed to.
He seems to have turned it around and hopefully the people of the UK will start to think about voting for Labour again.
I've spoken to a few of my friends that are very left (I'm actually pretty left but think of myself as a bit of a centrist - not because my views are centrist - but because I think that the very left and centrists parts of the Party need to get on for the good of the Party)
Some of my lefter-leaning friends disagree. That have said they think Starmer is a 'Tory'. They reckon there is 'no difference' between Labour under Starmer and the Tories. They reckon that he's 'worse than Blair'
When I pull them up over this and ask them why if Blair was 'the same as Tories' things improved in many ways when Labour were in power and why things got much worse in 2010 onwards when Labour were knocked from Power.
They tend to get a bit sniffy and/or angry. But seem massively angry with Starmer (or more likely pissed off that their cult leader was ousted.) We've agreed to stop arguing about it because I can't see us ever agreeing. I want the Tories out. We can worry about policy and other stuff once they are out - but Labour need to get them out as the country is getting worse by the day.
I consider myself mid-left
I believe in a mixed economy with a strong private sector - but with essential utilities like water/electricity/gas provided by suppliers who are state owned and run on a not-for-profit basis. I believe in better workers' rights and strong trade unions. I want expanded public services provided free or subsidised and properly funded. I want the vast majority of taxation to be progressive (in the economic sense). I want there to be a massive focus to combat the endemic levels of tax dodging amongst the wealthy, especially the abuse of offshoring & trusts, and the tearing-down of the secrecy-walls in the BOTs/CDs.
Do I think a Starmer government would implement these? Sadly, no. But we've just had a leader who took the party leftwards and he made a pig's arse of things. As you've said, this government is destroying the country and laying the groundwork for more destruction, along with deregulation on a huge scale (ie, removing protections for workers, the environment, consumers). We need to get them out next election or they will cause more harm than that evil bitch The Thatcher did.
I voted Starmer to be leader even though I'd prefer the policies that someone like RLB would follow. I believed he would work to, if not unite a fractured party, then be inclusive of the substantial leftist wing. I've been disappointed in him in this respect. But I'll still vote for his party - which is something I didn't do for any NuLabour elections*
* the caveat being I am in a very safe Labour seat and was able to protest-vote without consequence
