I genuinely defend Corbyn because he has become the most vilified man in politics in my lifetime, undeservedly, while others, guilty of greater undemocratic crimes, get off scott free.
I believe the main reason that he hasn't played the game is twofold, firstly, it isn't a game that has to be played, the westminster bubble is self feeding and his rhetoric is threatening that, he has tried consistently not to be drawn into the ego trips and name calling that allows the career politicians avoid their responsibilities to the electorate and lets them continue with their self serving practices.
Secondly, he has had to contend with those careerists within the labour party who put themselves way ahead of maintaining an opposition. The timing of the 'coup' is testament to that, straight after Brexit, when a concerted effort should have been launched by a united party to tackle a conservative party in disarray. It could have waited, if they were so determined, until conference season.
Given all the distractions it is no wonder that an organised approach hasn't been laid out. Where the blame for that lies is what is creating the arguments.
