the simple line is this,
If you beleive that animal testing is wrong then you should never take any drug connected with it. Ever taken an Aspirin or Paracetamol?
I can bet that if a person who is anti-animal testing is diagnosed with a life threatening disease and they have to take medicin/drugs that were tested on animals in order to survive they would do so.
I watched my Gran deteriorate due to Alzheimer's. It is not a pretty sight and one of the worst things I can imagine happening. Any research that needs to be carried out on animals to help cure or relieve the symptoms of Alzheimer's is worth it.
Animal "rights" activists are nothing but thugs. If they don't like testing to be carried out on animals they should volunteer themselves for testing.
