I'm no Corbyn fan.
Which is an understatement.
However, not going into 'talks' with May is definitely one of the least worst things he's done.
Those 'talks' are an exercise in providing a fig leaf of democratic process for a PM who has negotiated in an implicitly authoritarian style - and shoes no signs of stopping.
It could provide a fig leaf for worse: a seemingly 'X-party' group providing a fig-leaf for a 'national emergency' government that is as hard right and authoritarian as we fear.
We know what getting into bed with the Conservatives does for other parties: the Liberals carried the can for Conservative policies. It has virtually finished them as a political force. They've been destroyed. And look where that has taken us.
It wasn't fair. But the Conservatives are good at this game and have a powerful right-wing press behind them.
Caroline Lucas is also insisting on 'No Deal' being taken off the table as her 'Red line'. Admittedly, she's 'going in to talk' to present that. But ... we'll, I hope she sticks to her guns.
The problem, for Corbyn, is that he has been stupidly and ridiculously silent about the importance of 'No Deal'.
As a result, it just sounds like fatuous awkwardness now. And can easily be presented as such.
The line disseminated by unofficial Corbyn outriders is that Brexit is less of an issue than austerity. And that, clearly, is s line from within the Corbyn inner circle.
It echoes what Corbyn has done: PMQ after PMQ, public appearance after public appearance, his 'attack' has been to ignore Brexit and go on about domestic austerity policy.
The Corbyn outriders have even taken to attacking anti-Brexit speakers as people who don't care about austerity: 'You go on about Brecit! That's because you are middle class elite who don't care about homelessness!!'
It's ridiculous.
He should have been calling out No Deal for what it is: a disaster that will impact on the poor, hardest.
A proof that Brexit is a right wing revolution that we must fight.
A disgraceful negotiating ploy, where May is a deranged terrorist, sitting in a room filled with explosives, knife to the throat of her electorate, threatening to blow it all up and take everyone with her in an orgy of economic blood-letting.
He didn't do that.
He permitted, he enabled, the normalisation of No Deal.
And you get Labour supporters and Corbyn supporters telling you that No Deal is fine - a road-clearing to permit the entrance of the socialist nirvana.
Which is insane.
It's actually, properly insane. People who think this need help realigning their rational thought processes and their libidinal thinking. They need therapy.
But Corbyn has enabled it.
And, consequently, his throwing 'take no deal off the table or I won't talk' at this stage looks utterly shallow.
Which, frankly, it is.
