No, I am completely serious. There is nothing whatsoever unprincipled about having a set of policies which are aimed at a larger section of the populace than the left wing, however much you personally despise anything which isn't left wing.The fact is, your view is in the minority (as demonstrated every time Labour go to the polls with a left wing agenda), but you demand that they represent your minority viewpoint rather than try to appeal to, and work for, a more representative sample of the British public. Fine. As someone said.......Corbyn wins and the Tories are in power for a generation. It's clearly very important to you that a left wing agenda is represented in opposition, and that's exactly what will happen.
In contrast, I deplore the lack of a viable opposition. I think it really important that the governing party is held accountable, and that there is an oven-ready alternative sitting waiting for the opportunity to take their place. Although I voted Tory this time (for the first time), I would hate to think of any party being in power for more than 2 terms, because they always get lazy, do stupid things, and start fighting with each other, whoever they are. So, unlike you, I welcome an electable alternative. You just want someone to say things you agree with, whereas I want a viable opposition, and then a competent government when their turn comes.
