Given that this thread is about Corbyn, it can be no surprise that the relative behaviours of Tories and New Labour are being compared alongside the Corbyn position. You may regard the latter as being excessively left-wing, and be that as it may, but the fact remains that, in comparison to what Corbyn & Co are saying (and which appears to have the support of a lot of the grass-roots membership, there is not a huge gulf in practical terms between Blairite policy and that of the Tories. We have seen, time and again, Labour refuse to present any significant opposition to even the most vicious policy initiatives from either the present government or the Coalition, and many of the leadership candidates (remember, the ones who, put together, still polled less than Corbyn managed by himself) have also made it clear that they support much of the present government's strategies on austerity, welfare, etc.
You may not like that - and that is your right - but you really aren't going to get anywhere with a nitpicking approach to Corbyn's policies while you're still apparently so ready to whitewash the ills of his competitors in "blue" Labour.
