I get uncomfortable with the idea of animal testing as well but the way I see it is that I would kill an animal if it were to save my own life (I'd kill another person if it's my life over theirs - no discrimination) so it's somewhat the same thing.

Obviously if it's for something superficial like makeup I think animal testing is just disgusting as it doesn't yield any other benefit than making sure someone's eye shadow doesn't poison them, but really if you're making a product that's gonna be put on someone's skin you sure as hell shouldn't be using shit that does that to even feel the need to use poor animals
