I posted the comments below on a different thread but I'm minded to post them again here:
When I joined the LP many years ago my CLP was a "safe space" for robust but good natured discussion. All viewpoints were welcome at the table and given considerate thought. Members might disagree on certain issues but had a collective empathy with broader aims.
It was a place that tolerated the then hard left "outliers" like Corbyn who were allowed a voice and were respected for their stance on various issues and similarly centre left viewpoints.
Ironically that same level of respect has gone since JC became leader. There's no tolerance or space for discussion.
My CLP was overrun by predominantly 20 something male SJW's whose contribution was policing social media and shutting down debate in meetings. Long standing members who did actual work for the party (canvassing, admin etc) were treated with distain.
When I and a number of other long standing members finally had enough and left what do you think the reaction was?
A review of why? A discussion to try and change our minds? An offer to find compromise/common ground? A serious discussion on why so many long term members found their own party toxic?
No, the fuckers threw a party to celebrate "freeing" the CLP from the "bigots" and "blairites" (and they call the Tory's the "nasty party").
The grass roots level of capture around purity/identity politics, driven largely by middle class men is a fundamental problem for the party.
Their arrogant assumption that they hold the social moral high ground absolutely blinds them to the fact they are out of touch not only with the wider electorate but former party loyalists whilst simultaneously patronising the people whose votes they need in the belief that they simply need to be "educated".
The comment above about the Daily Mail absolutely sums up that mentality.
Like it or not it's the paper that has the largest circulation in the U.K.
Dismissing it and by default it's readers as "vile", "right wing" and "nonsense" fails to acknowledge the fact that a significant proportion of that readership are the very people the party needs to win over if they ever hope to be in govt again.
People don't vote for a party that repeatedly demonstrates that they despise them and treats them with contempt stemming from an false arrogance that they have some sort of moral social supremacy.
