So where did the smallpox vaccine come from ?
This is, frankly, a lot of hot air. We all set our moral standards. But Pete is the only one here with a defendable position. Either you defend the man that gave us the smallpox vaccine, or you fight against animal experimentation. The only exceptions are creationists, but in some ways their view is similar to the likes of Pete. Its okay to be cruel to animals because that will help us superior humans in the long run.
You may have noticed but I loath media sensalistaion, almost as much as I feel sorry for the people that get wrapped up in it but don't even realise that they are.
