This may be tough to hear but some poeple don’t give a shit about animals.
Is that arrogant? Fuck yes. Is it hypocritical? From most people, yes. Is it wrong? Lol no, humanity rules over earth and I really don’t see why we should (potentially) torture our own population in experiments rather than species that largely lack self awareness and often have problems with object permanence.
Animals are animals and unless one of them writes me an essay about how all of this is wrong in its own language I won’t change my mind on that. The only species coming even remotely close to us in intellect and mind are dolphins and octopi, neither of which are commonly used for animal trials of anything except puzzles.
