Well, no - since my point was that the perception of UKIP is already that they are a bunch of racists, the outing of racist candidates just reinforces the belief (call it a bias, if you like). There's no such widely held preconception of the Labour party being an organisation of nonces, so it's easier for people to discount the outing of Labour party kiddie fiddlers as being exceptions.
So you're a hypocrite then, thanks for clearing that up
