I'm not backing him though, In fact I've said on regular occasions I thought the PLP would wipe him out before now, that his politics are just warmed-up Keynesianism etc. I'm mostly in this for the entertainment value.
The difference here is I can see a car-crash when it's on its way, in which a PLP full of arrogant political wonks take down their most popular member in favour of exactly the sort of liberal Westminster bean everyone hates. And they'll do so in a poisonous manner that'll lose them the unions, the remainder of the active membership and quite probably the next two to three elections, while also essentially killing off the last remnants of left influence (because let's be clear about this, if they win now, a left-wing candidate will never happen again).
You on the other hand have nothing other than laughable characterisations of someone you've clearly never met, designed to make you feel better about backing an anti-democratic coup against the only left-winger you'll ever see in charge of Labour. You have no plan, no alternative, you've not bothered to analyse the consequences, all you have are boring, contentless appraisals of his motivations and capabilities. And that I find irritating. Why get worked up about Jeremy failing the left if all you want is for the Labour right to sort everything out for you while you merrily avoid having any original thoughts of your own or involving yourself in any concrete way? What's the point?
