A dog that has rabies probably will do things it wouldn't do if it didn't have rabies. But that doesn't change the fact that it has rabies.
What I like about sceptics is that in good science you need critics that make you think: 'Crumbs have I made a mistake here?' If you don't have that continuously you really are up the creek. The good sceptics have done a good service but some of the mad ones I think have not done anyone any favours.
