They are horrible, ugly, above all insular, and as my Mum tended to say when I was little and I got into arguments with my sibings "If you are not careful it will end in tears!" (See here, here, and here)
Personally, at the risk of being flippant during an inappropriate moment (apologies in advance therefore), I would have thought that simply being a Young Conservative in the 1980's was enough of a slur, esp simply being a member of the FCS, but C'est la vie!
I agree with Iain Dale that this has to stop. One only has to see the blogosphere in the US to know how nasty and unpleasant this can be in a way which diminishes everyone involved. As Paul Linford has stated, there has been enough nastiness flying around from a few on both sides. In any case, I would far rather get angry with the Daily Mail for their mentioning a member of Blair's family in today's edition of their paper.
I have been around party politics long enough to know how some people have a dislike of some forms of ideology and it's representatives that borders on the pathological. The problem is when all that anger explodes and is aimed towards individuals. Two rules to remember in blogging however. 1) If you write under a pseudonym and your blog is popular, beware, because some people will be out to expose you and it will be relatively easy to do so and 2) If you throw mud and accusations around, be sure that you will p*** off enough people to start to do the same thing towards you. This is not directed at Guido as such, but rather any aspiring blogger, esp in the field of politics.
