I can see the concern on your side. I do however argue that in this day in age new drugs and advancements in curing diseases requires some kind of testing on biological living creatures. Animals are more similar in function and DNA than say an insect is. For the best results to finding cures for diseases we need to use animals. Will you still feel the same if one day through preclinical testing the cure for a major disease is discovered?
I would however state that animal testing should be done in a very humane way in a regulated environment to assure their proper treatment. Brutally abusing and animal cruelty should not be accepted. Animal testing gives mankind key knowlege that could unlock cures or important methods that can save many human lives. It has already resluted in saving human lives.
