Ofcourse , problem is they cant even agree to that within the party .
They can't, but then the time to debate it is now, surely, and get the rough bits out the way in good time before an election. Hopefully, both sides can accept whatever the result is, and fight as one from that point... but then that is the problem with allowing representation from everybody really, everybody sticks their oar in!
You know, I've never done political conferences, but have done a number of pretty large conferences in the past as part of my, errrm, career(?) Basically, you can find whatever view you like if you seek it out, as people highlight a wide range of views, and policies, and agendas. Maybe they do need a spot more grandstanding than they do, a bit more oratory but... the fight overall is with Conservatives and others. What I'd always liked about the Labour Party was the way anybody could challenge whatever the leadership wanted to do. What I've liked less is the way they keep doing it, regardless!
It would be nice to think Labour would actually learn from the Conservatives(!) get the pain out the way now, be cohesive by the time of a general election. I know that might be a naive thought but, again, it's pragmatism. In my own head I've been proved right we'd have been better off with a Corbyn government than the current lot, so I wish people had backed him more at those points. Same applies now, really. We have the leader we have, don't sidetrack him by making him use too much of his energy fighting his own party.
