If I want a fight, uk_politics is always worth posting to. Alternately, flydanman has always been their resident troll. Personally, I tend to end up going for authoritarian NuLabourite, they're more fun to wind up, Tories are generally either too easy or actually smart, depending on whether they're Boris style liberals or Maggie/Tebbit style 'victorians'.

There's always the more widespread blogs; ConservativeHome is always a giggle to read (so stupid), and devils_kitchen has a fine line in crude insults to all things Left. Especially Polly Toynbee.

And I'm not trusting any 'merkins, but how the creator of something wants it to be used is irrelevent; whole point of freedom of choice is that I'll do what I want with it, which is whisky and lemonade on ice, and salad cream with every meal, thankee muchly ;-)

(also, my net connection is really dead, so if I disapppear, it's because I gave up)
