Let me count the ways that this is a stupid & hypocritical argument.

1. Does the modern Labour Party have a working class membership, or is it increasingly a gentrified collection of hooray far lefties, v. comfortably off older public sector workers and students? Hmm... https://twitter.com/FisherAndrew79/status/1245348506258243591

2. If 'current level of mass working class support' is your measure of political validity Andrew, then I look forward to you joining the Conservative Party soon.

In membership and electoral support, Corbyn's Labour were/are a middle-class party

3. It's true that BL is a v small strand within the current Labour Party - but that's a reflection of the modern Labour Party, which has cut itself off into a bizarre little bubble of insane social radicalism and identity politics (which is why the working class mostly vote Tory)

4. BL's approach - economically left, patriotic, socially moderately conservative - is, according to every survey, where a massive % of the British public is. If Labour took any notice of BL, every indication is that such an approach could be v popular, esp. w/ the working class

5. The 'Maurice Glasman is a Cambridge-educated peer' argument is shitty ad hominem stuff. He came from a working class Jewish background and got into Cambridge (so what?), Ed Miliband made him a peer because of his community organising work, campaigning for the Living Wage.
