I went to a grammar school and managed to turn out rational and still loyal to my class, so I don't think we can blame his schooling for the fact that he's a cunt.
I've said this so many times now I feel like a fucking parrot, but here I go again:
We don't live in a functioning democracy, IMHO. If we did, then as members of the electorate we'd have a damn sight more power to make sure that our MPs actually bothered to represent the views of their constituents in Parliament, rather than the current sham of pretending to do so, and merely representing the interests of their party and/or their party's funders.
What we live in is a pseudo-democracy, a phantom so far removed from the true meaning of democracy that it's a vicious joke.
As in many "safe" seats, the greatest force behind Purnell being voted in for his constituency was the fact that he represents the Labour party. A syphilitic monkey could win the seat in such a place, where tradition seems to count for more than sense.
