A lot of that stuff is known as humane washing in the animal rights world. Exploiting and inflicting suffering onto animals is almost always unethical. The only way to treat animals ethically is to not test on them at all.
Would you still hold that opinion if you contracted an illness that can be cured as a result of animal testing?
I’m not OP but speaking for myself, yes.
Well, fuzzy cute ones anyway. Surely we can test on E-Coli? How about slime molds? Maybe the occasional insect? What about shrews - they are nasty and mean.
