Well, how many other humans would you murder to save your grandma's life? Or your wife, your children, someone you love? What about terminally ill humans who have < 1 year to live (assuming the particular testing results won't get skewed by their particular ailments)? How about prisoners sentenced for heinous crimes? What about humans who are "not productive"? People who have been sentenced to more than 10 years? You might draw the line at other species. Someone else might draw it differently to not do experiments on intelligent species like whales, dolphins and primates (who are used in lab experiments too). Or someone might include the categories I mentioned above in the list of test subjects. The big second question is the effectiveness of transferring the results of tests from animals to humans. Coldly speaking, while there are experiments that yield useful results on animals, there are also extremely pointless experiments that are done for the sake of doing. I won't go on and on but to your statement about " I am willing to sacrifice an insane amount of animal lives in order to save anyone human", would you do it to save Hitler (who is a proxy for someone who, maybe, you should think twice about saving)? I agree with you about replacing the meat industry but we can do multiple things as a species at the same time. We can work on replacing the meat industry, working on alternate ways of testing drugs, on understanding animal communications and language (and we keep finding new indicators of intelligence) and on reducing our footprint as we get technologically and hopefully culturally more sophisticated.
