Re: "No, No, No. Let me resign..."
Well Labour is another kettle of fish.
A leader supported by the "members"; a useful number of whom joined so that they could support Corbyn, rather than having any affinity with the Labour party as such.
It is not the first time that "entryists" have taken the reins of the Labour Party and made it unelectable. But these people don't care about being elected into power. They are waiting for the masses to rise up and take control of the means of production. They want to "raise class conciousness". And anything that gets the workers stirred up is grist to their mill. Come the revolution they expect to be marching at the front carrying the banners. It's the Marxist view of History.
Unfortunately the normal view of history tells us that if the moment did come they are more likely to be among the first hanging from the lampposts.
