JC took a hammering when he was elected. He faced so much backstabbing and bile from within his own party Labour basically gifted the last election to the Tories. If they'd just said "Oh well, JC is leader now, let's get behind him and give him the benefit of the doubt for a year or so" then we could be under a Labour government right now. Instead, we had mass shadow cabinet firings, votes of no confidence, and Labour party politicians publicly ragging on their own party leader for the better part of two years.
He then took even further flak when he decided he had had enough of this shit, and consolidated his power by firing every fucker who was trying to stab him in the back and putting in place people who would actually support him. Apparently this was a "purge" rather than "common fucking sense" according to the newspapers. You can't run the second largest party in the country with every MP with delusions of grandeur trying to unseat you - witness the Tories and May being completely unable to sack people like Hunt due to her own wobbly power base.
So great, JC, you took the flak, you survived, you gained control of the party, and dragged it kicking and screaming into shape so that it actually presents something resembling a unified whole, inasmuch as possible. Big props for that, you have my respect for managing to deal with everything that was thrown at you.
And then you did.... what?
Fucking nothing.
No meaningful opposition to anything the Tories have done. No opposition to Brexit. No answers of your own. No public speeches about your alternative plan. You've got your own personal beef with the EU which means you're okay with Brexit going through, despite the huge and catastrophic damage it will inflict on this country. Not only that, but the damage it will inflict on our poorest citizens. The people the Labour party are supposed to stand up for. You're so focused on winning the next election you're willing to let the most destructive event of this century, the worst thing to happen since WW2 go utterly unchallenged.
And for that I have nothing but contempt for you, JC. You're throwing out policies that would be difficult to fund even under the status quo (however praiseworthy they are) while ignoring the fact that Brexit is going to fuck the economy so completely we're going to have to endure another 10 years of Austerity, which is already killing our people. Police cuts are killing young people in London. Social care cuts are killing the elderly. Mental health cuts are killing the vulnerable and abused. NHS cuts are killing sick people of all ages. What part of Brexit is going to solve this? How does destroying our biggest trading relationship get us more money to deal with these problems?
It doesn't. But you want to chase your personal grudge against the EU and win the next election, rather than help the people who need it most. I expected it from the Tories. I didn't expect it from you.
