The Corbyn fans really need to let it go. I voted to have him as leader twice. I was wrong. He lost, badly, and his time is gone. They need to stop the petty booing and name-calling of the current leader, or leave. In politics you very rarely get exactly what you want. Politics is the art of the possible, and you either take what improvements you can or get out. Jeremy couldn't handle the media. Yes they were disgraceful but he had his chance and buggered it up. Time to accept it and move on.
This.
The Centre/Right of the Party acted disgracefully to undermine Corbyn for two years when he first came in. Some of them were not just trying to undermine Corbyn, but working to negatively impact the Party as a whole simply to make it look more damning for Corbyn. A very small number even carried on in exactly that same vein even after the 2017 GE result.
The Left were furious and with some justification.
Now the Left are doing the same.
Both were/are wrong, but the sequence is important. The Left have seen and felt what this does for the Conservatives, it is absolutely fresh in their memories. They have just been given a clear opinion from the general public on them. Whatever the unsavoury and unprincipled behaviour from the right was, at least they have the excuse of being correct.
The Left, rather than accept they did a poor job and retire with dignity to lick their wounds and reflect on how to do things better or differently in the future, for the greater good of the public, are instead acting as poorly as the Right did, which they moaned furiously about. So they are not only as unprincipled as their colleagues, they have the added deficiency of hypocrisy.
And also, they were rejected by the public, yet again. When will they learn?
