It wasn't. It simply wasn't. It was all about the support for the Palestnians on the part of the Labour left (in my vi=ew, overdone on their part, but nonetheless genuine), which the Israel lobby blew up into a huge AS thing, plus the Blairites in the PLP and party machine using as a stick to beat Labour with. It was a hatchet job.
a bit more than that really, the crank left with their obsessions over ‘bankers’ and ‘global elites’ and the unusual alliances within such circles became drawn to the party with Corbyn at the helm, in part because of the occasional signal he’d given them that such views were Ok (such as that mural thing, clumsily not paying enough attention at best). Not something at the core of the party or his supporters at all, definitely overblown by cunts to attack the left, but it was there and needed confronting. They didn’t really do a good job of this, whether through internal sabotage or occasionally not wanting to call out and punish longtime allies that put their foot in it. But anyway, that had almost fuck all to do directly with them losing, other than causing disarray and division in the party which was the point of it.
