Sophable .... you are like a one-woman outrage-grenade!!
Surely Prolesworth is allowed to express indignation at one thing, without that indignation immediately being collapsed into support for another?
By that logic we would never be able to express delight/indignation at anything piece by piece - we'd have to sign up for support of "our" (!) party without permission to criticise/praise any individual piece of legislation/policy/etc. on a piece by piece basis.
It's important that we are allowed to hop about in our criticisms/praise. Anything else is quite "tribal", and it closes down the possibility of meaningful debate:
"Oh you can't criticise this, because you agreed to that ... you thought x was good, therefore you have to say y is."
Erm, no, we don't. And it's important we never allow ourselves to be conned/coerced into doing it or to allow others to misrepresent our assent to "x" to imply our endorsement of "y".
I don't know why, but you do seem very keen on trying to represent the multiple, and quite fragmented voices of "lefties-who-are-pro-bits-of Labour-policy" as a univocal mass, and sort of herding us into a massification-without-dissent that we are quite keen to escape. It's odd.
