I prefer Stewart Pearson's analogy about renovating a house, in the last episode of The Thick of It.
I've spent ten years detoxifying this party. It's been a bit like renovating an old, old house, yeah? You can take out a sexist beam here, a callous window there, replace the odd homophobic roof tile. But after a while you realise that this renovation is doomed. Because the foundations are built on what I can only describe as a solid bed of cunts.
