Grandad your post indicates that you support a Corbyn far left puppet Government with Momentum and the Trade Unions pulling the strings. Have I got that right?
The Parliamentary Labour group you believe "is an integral part of the wider Labour movement in the UK". The indications are, that far from being integrated with the grassroots Labour movement or relating to the "wider Labour movement" outside of London, the Parliamentary Labour group is divided and not all leaning to the far left. The concerns of the middle to left Labour Parliamentary group about the far left's attempted take over of the Party is not a secret.
The discontent in the wider Labour movement or grassroots Labour voters outside of the London bubble is there though being suppressed by the far left militant activist group Momentum, along with it seems now the The Unions. It may be the Unions have sensed a main chance, perhaps seeing power through a Corbynist far left Government as their last chance to run the country through the backdoor.
I realise that you say you "do not support all that is being stated and proposed in the Labour party at present". However what is concerning is the impression given that as one, the Parliamentary Labour group and the overall Labour movement in the country are united, and it is their united "views that are in prominence once again for better or for worse".
From what you say, this would indicate, that the entire Labour movement, inside and outside of Parliament acting as one, are far left Corbynist supporters, intent on getting into power as a Puppet Government, controlled by the Trade Unions and Momentum activist Trotsky/Marxist group.
The attitude of, "for better or for worse", is a terrifying concept in this scenario. Indicating that power at any cost is all that matters. The attitude that we might get a communist Puppet Government, but Labour will be in power. This assumes that there are no moderate to left Labour voters, that they are all far left wing, or, if that is not true, the moderate to left wing will just go along with it, vote for Corbyn at a future General Election, to get into power, whilst holding the notion that it can be sorted out once in Government, when the far left can be controlled or got rid of. If this is the right interpretation of what you have said, then in my view Labour will collapse or divide. I see that this might happen anyway. I see no evidence that the Labour movement is acting as one as you suggest. Many, many Labour people recognise that the far left is not how they see socialism in the UK.
Interestingly whilst reading your post and responding, I saw shades of "Militant" and the 1985 stand that Neil Kinnock and the grass roots Labour movement took against "Militant". Kinnock's speech at the Labour party conference in Bournmouth was judged outstanding by his own and other political party's. Here it is:
At the Labour party conference in Bournmouth in 1985 Kinnock stood up for the grass roots Labour voter and membership.
The report says: ‘He [Neil Kinnock]then built up to an attack on the Militant Tendency;
" I shall tell you again what you know. Because you are from the people, because you are of the people, because you live with the same realities as everybody else lives with, implausible promises don’t win victories. I’ll tell you what happens with impossible promises. You start with far-fetched resolutions. They are then pickled into a rigid dogma, a code, and you go through the years sticking to that, out-dated, mis-placed, irrelevant to the real needs, and you end up in the grotesque chaos of a Labour council hiring taxis to scuttle round a city handing out redundancy notices to its own workers.
As Kinnock spoke, Hatton shouted “Liar!” from the back of the hall, prompting the Labour leader to address him directly:
“I’m telling you, and you’ll listen – you can’t play politics with people’s jobs and with people’s services or with their homes.”
Eric Heffer walked off the stage in disgust, apparently with tears in his eyes. Immediately after, the Labour establishment rallied behind Kinnock. Healey called it a speech that “will change the centre of gravity within the movement” while Barbara Castle exerted that it was the best leaders speech she had heard in 25 years.
In her memoir Fighting All The Way, Castle went one further, claiming that it was “the most courageous and effective speech i have ever heard a politician make.

All that is needed now is one unafraid voice to speak for the real Labour movement, the one that is outside of the London bubble. There are a few MP's waiting in the wings, will they have the courage that Kinnock had, to stand/lead for the Labour party of the grass roots in the face of a far left coup -de -etat. Let's hope so, the "better" is unthinkable and the 'worse' is unimaginable as far as I can estimate.
