To a point it's an indictment of Corbyn, and his unwillingness to find some kind of middle group between himself and the moderates in the party. At this point in time there is absolutely no good fecking reason to be talking about the plight of Palestinians, about our NATO membership, about unilateral nuclear disarmament or any of the other vanity projects of the far left.
It also says a lot about the political disengagement of the British public however who keep voting Tories back into power despite them draining public services of funds, and fundamentally undermining the NHS which the public almost unanimously support. There's a genuine mass ignorance about what parties actually stand for, what they do, and what is a realistic expectation of them. Vast numbers of people don't know shit about politics, don't understand the issues and the policies but believe their own often deeply childish interpretations must be right because of 'common sense'. It's the same in America, which is why they have such a ridiculous, braindead asshole in the White House.
I've got a long running theory that this is a cycle. In times of national crisis people start to focus on politics and the genuinely important things that effect everyones lives and then we see genuiine positive change in the wake of the crisis. Then as people become comfortable in their lives, they disengage and focus on their own personal circumstances and so over time politicians can operate under far less public scrutiny. Propaganda becomes more important than public engagement and policy and the level of leadership declines as liars and salesmen replace genuine statesmen and women. This inevitably leads eventually to mass public disgust and disapproval of politicians, which opens the door to the next group of populists to come along and feck everything up and cause the new crisis to reset the cycle.
That's my theory anyway.
