Torturing kids for fun is wrong everywhere, always, no matter what your tribe says. If that's not an objective fact, nothing is.
Even if evolution wired us for empathy, the fact that harm feels bad across brains makes kid torture wrong independently of opinions. Otherwise ethics collapses into 'might makes right'.
Agree with moral realism. Another angle: rational reflection plus empathy reveal objective duties to protect the vulnerable, universal beyond tribal lines.
Agree that torture is universally wrong; but moral realism also demands universal education and gender equality, for reason flourishes only when women share rights.
