I think that treating anything that can feel pain as a 'laboratory test organism' is the sort of thinking that leads to gross human rights abuses and de-humanization in general. There's not a huge gap between ignoring the screams of small animals/primates and ignoring the screams of another human.

I'm by no means totally against animal testing, but I have to disagree strongly with your callous attitude toward the process. Animal testing should be done as humanely as possible.
