God discussions like this make me despair.
Most people, Labour members and not, are perfectly capable of understanding that the "far left" and centre left need to work together, find solutions from across the range of "left" that are appropriate to both left wing principles and the need for electability. Most people are capable of discussing the issues involved and arriving cooperatively - via democratic processes within Labour party branches etc - at solutions.
This is why a considerable majority of Labour members - who must therefore have included many who supported Jeremy Corbyn - voted for Keir Starmer to be party leader. He appeared to be the right person to take the best of the party's policies and principles and present and advance them in a politically pragmatic way. Unfortunately it was all lies, and once he had power the "purge" started, contrary to everything he said in order to get it.
The problem is not whether Labour should be left, far left, centre left, put-your-left-hand-in-and-you-shake-it-all-about or anything else. The problem is that "purging" - the suppression of dissent, the suspension of the party's own democratic processes, the blatant exercise of dictatorial power from the top and the complete disregard for the most basic natural justice or logic in disciplinary processes - is considered the right way to achieve it.
Blair didn't do that. For all he is vilified by the left, he at least took the party to the right by making the arguments, patiently having the discussions and winning them. Corbyn didn't do it either, he did the opposite - attempting to increase the robustness of grass roots party democracy. Maybe this is the only thing they had in common.
Something fundamental has died in the Labour party under Starmer, and it's got nothing to do with whether the left or the right "wins". It's got to do with what it means to exercise democracy, beyond hauling your arse off the sofa to get to a polling station ocne every five years and choose between two parties that are basically the same as each other.
Try reading about how Diane Abbot's case was handled without thinking about whether you like her or are on her "side" or not, but just about whether that's a good way to go about administering a political party or treating an elected representative generally. That after all is how justice is supposed to work - to be objective, and accord the same basic rights and considerations to everyone. Then consider that it's far from a one-off: the entire Labour party disciplinary machine operates this way, as a plaything for factional warfare by autocrats.
It's so sad that people actually think this is OK, as long is it ends up putting the people they like in power (or rather, what seems to be more the point, keeping the people they dislike out of power).
