Labour support comes from 2 camps traditional working class who are typically the victims of tory policy (but have been brainwashed into brexit support) and progressive urban elites who object to the right wing / alt right mindset. The idea that Labour have to choose one side or appeal to both is where they went wrong - they should stick with center left progressive politics and leave the BSing to Boris. Brexit will be a problem not a solutiion going forward so the idea that you pick a leader to back it is plain wrong - they need to think ahead.
I'm afraid that your party now encapsulates the views you state, and will never win elections because of them.
The likes of Starmer and Thornberry have spent the last 42 months condescending to working class folk, and have made
the same, or definitely inferred, similar comments that their voters have been 'Brainwashed into Brexit support.' Also, these people are not going to
all of a sudden vote for someone because it's a woman, from the north, again it's another example of identity politics, that has
infested the party, Johnson could not be more different, yet has gained the votes of these people, and in enormous numbers.
They simply have to recruit someone who is for Brexit, it's happening, remain is dead, gone, and yet we're still hearing the same
arguments against it, 'Brexit will be a problem' etc; Whether it will or not, is now irrelevant, the fact is we're getting it.
Thornberry has just been on TV, listening to her, with mounting incredulity, telling everyone that black and white, is really pink and green,
and was still waffling claptrap about confirmatory referendums, was unbelievable.
Labour now, with the candidates being offered up, are done for.
