If you (general you) are arguing for a "pragmatic" "electable" Labour Party for 2020, as Toynbee is, as Hertford is, then yes you are arguing for a liberal Labour Party, to pretend otherwise is ostrich behaviour. Hertford claims he wants a more equal society, no doubt so would Toynbee and all the Labour MPs, but those desires are fucking meaningless when your actually actions are in the opposite direction.

post summed up the situation brilliantly, the Labour Party has been neo-liberal for 30 odd years, the hollowing out of its vote has been going on for at least as long, you are not going to change those things in a couple of years. This is going to be a decade(s) long fight and it's very likely that things will get worse for the LP before they get better.
Utter ahistoric nonsense, were you asleep during the last 30 years? The unions have nowhere else to go (and a number have already indicated they want to remove Corbyn and want the party to become 'electable' again), the members don't have the ability to deselect and can just be ignored as they were for much of the last 30 years.
In the 70s/80s you had a well organised left-wing body in the membership with a higher proportion of sympathisers in the middle and upper ranks of the party and they weren't able to stop the party becoming neo-liberal. It's utter lunacy to think that in 2017 where a similar type of organisation doesn't exist, where there a handful of supporters in the upper/middle ranks, where there's been 30 years of bureaucracy and rules developed precisely to stop any challenge to the party establishment that you had a better chance than in the past.
