'Surely if we've learned anything from the Corbyn 'moment' is that it is next to impossible to change anything much from within the British electoral system.' - good point, the 'hope' that John M mentions below could in fact be the most damaging thing Corbyn et al could offer the British public at the moment if that means our energies get diverted down another ineffective cul de sac instead of direct political engagement such as strikes, direct action, organised boycotts, building alt media, sabotage, etc. People fall asleep and renounce their agency when they have 'hope'.
