You're saying that going as far to the right as necessary to win elections doesn't involve a great shift in Labour's stance. Of course I agree, more's the pity.Yes, but your fertile imagination, and your distrust of anyone to the right of Karl Marx, has led you to think that this involves a great shift in Labour's stance. Of course, it does nothing of the sort. Furthermore, you dress it up as going to the right, whereas I would characterise it as moving further towards the centreground of political opinion. Hell, staying exactly where Miliband left the party would be far better for Labour's chances than following Corbyn's lead.
Furthermore, the current leadership seem to think it's improper even in principle to oppose the Tory government. In this, it has acquired powerful support. Here's Tony, from today's Guardian, voicing his views.
Opposing Tory welfare cuts is like club-wielding cavemen blaming somebody else.... it is the oldest politics in the world. It’s the politics of the first caveman council, when the caveman came out from a council where there were difficult decisions and pointed with his club across the forest and said: ‘They’re the problem, over there, that’s the problem.’ It’s blaming someone else.
